A Refresher on Securing Race Sponsors

0

2025 PWC Racing schedules are flooding the social media feeds; the 2025 Boat Show Season is underway, and even though much of the country is a bit of a deepfreeze right now, there is little doubt that many PWC racers are starting to get impatient for the start of another race season. 

And while there are a list of “must dos” for each racer to get ready for that season – from physical training for themselves to upgrades and modifications for their PWC, not to mention the mundane tasks such as trailer upkeep and gear checks, there is one aspect of racing that is not talked about near as much – sponsorships. 

While sponsorships may not be the goldmine they once were, there can be no denying the fact that securing sponsorship is a key component of funding your race addiction. 

In a 2015 WCJ article, Roger Berkon shared some advice for racers who are looking to secure sponsorships before the 2025 race season, and we thought now would be a good time for a refresher. 

At today’s “touring series” level, personal watercraft (PWC) racing is not only becoming a serious sport, it can easily become a business and an investment. It can be an investment in a state-of-the-art PWC, or two, support equipment, a hauler; an investment in team development, crew recruitment and travel to each of a minimum of twelve poorly scheduled geographically divergent race venues per season year.

Even the well-funded teams and riders are considering outside sources to fund their racing budgets. The outside sourcing, and the search for commercial participants (sponsors) and investors, must be done with the same research and consultation as any other business investment or capital expenditure. You and your outside sources have every right to expect a reasonable return; be it in hard dollars to your race team, or the benefits of brand development programs and campaigns that stimulate higher sales volume and increased traffic resulting in subsequent profit to your outside sources.

The point here is that sponsorship is a vital income source. You must develop this source with the same effort you put into your racing program; you must provide a valuable market service and or advertising vehicle in return for the sponsorship dollars. No longer can you attract sponsors or team investors with flashy graphics, creative numbers or smoke and mirrors.

In the PWC racing world of today, your off-water wars can be won incrementally by producing exciting, informative, efficient communications at every level of your marketing and promotional mix. This holds especially true when you are selling PWC racing. To accomplish this requires thorough knowledge of every aspect of the sport and industry; a carefully conceived strategy designed to impact each of your opportunity areas. These subjects are not the absolute function of advertising or sports marketing agencies. You must develop your own marketing and promotions person; someone that is close to or from within your own race team who can effectively and profitably reach each of your team’s targeted opportunity areas.

You must be aware that successful promotion motivates marketers and increases corporate participation; marketing creates the awareness and demand factors; advertising makes your prospective sponsor/commercial participant take that step toward the buying decision; and in this context the buying decision is “buying in” or making the sponsorship investment.

You and your team’s M&P person must follow a logical, step-by-step, approach in making your marketing effort pay off in maximum profitability. You must consider all available industry data, including trade publication surveys and national trade show profiles. This research is your only way to determine the targeted markets’ moods, actions, and emotional hot buttons.

You must maintain constant awareness of your competition off-water as well as on-water; follow their marketing and commercial participant solicitations; make on-site pit visits as well as in-shop visits and when the opportunity arises, use their events and promotions, as well as your own, as directional factors. In this way you will further develop your ability to attract sponsors and produce team income through commercial participation and promotion.

It is imperative that your race team be clearly positioned as the best available in the minds of your audience and your targeted market. This demands properly focused and consistent communication; an image that is positive and memorable, and performance on and off the water that delivers!

Any age-old misconceptions about PWC racing must be dealt with and dispelled. Fortunately, through the effort and continuing success of race organizers AquaX Series and subject-specific publications such as The Watercraft Journal, plus the never-ending support of manufacturers such as Yamaha, Kawasaki, Sea-Doo and high-end tuners RIVA MotorSports, there are few remaining negative misconceptions; however, never lose site of the fact that the developing new image and the real potential for commercial benefits in PWC racing are still unknown by most of your out-of-industry targeted markets.

Your overall presentation must be sophisticated, tasteful and in keeping with the desired image; your success will be achieved by impacting the key purchasing influences; namely the prospective sponsor’s perception, executive’s opinions, and the marketing team’s recommendation. Do not forget that the buying decision, in your targeted market, is based primarily on self-gathered data and the information you presented. If budgets restrict you to only one informational piece be sure to include a section designed as a guide to PWC racing. Keep in mind that the typical corporate marketing person’s experience with PWC racing is limited to the scant coverage on TV or what very little is in the local sports pages.

Position your race team clearly as the ultimate in the market, try a thematic approach; youthful, well spoken, the ultimate product or corporate representative; the finest PWC racing team in the sport today and you are totally committed to racing for “podium-finishes” in the best racing series. Capitalize on existing mystique through an image-oriented campaign in the appropriate media; create your rider’s celebrity, or perhaps you are owned by a South Pacific Coconut Plantation or your Crew Chief breeds porcupines in the off-season. Establish and maintain share-of-mind. Create and capitalize on all PR opportunities whenever possible, particularly with regards to your participation in the racing series and its related special events. Clearly communicate the advantages and benefits of an association with your team and the series.

 

Produce highly informative social media content in such a way that all key advantages are depicted, tell the story and effectively position your team in the minds of commercial interests and out of industry sponsor prospects.

It is vitally important that your team be organized in a business-like manner and is structured in such a way to properly receive and justify sponsorship income. You must stay focused on the commercial objectives of the sponsor/investor as well as your race team. And at all times consider your combined liability exposure and limit your risks as much as possible and continue the building and development of your team management, staffing and race equipment development.

To consider doing it any other way will lead to a very short, albeit exciting, venture into PWC racing lasting only as long as your financial resources or your willingness to keep writing checks. If you feel that you need help in any of the areas above, seek professional advice. It may make the difference that allows you to realize your goals in this wet and exciting segment of power sports racing.

IJSBA Releases Managing Directors Recommendations For 2025 Rule Book Changes

0

Yesterday, IJSBA released the Managing Director’s recommendations for changes to the 2025 Competition Rule Book. Each year, IJSBA requests input from the general public for potential rule changes. The input received is compiled and further public comment is solicited. These comments are integrated into a set of recommendations. This year, an ad hoc rule review committee was also created to make a set of recommendations independent of those from the Managing Director. The votes are being tabulated and will be presented to the public tomorrow. Both the Managing Director recommendations and the committee recommendations will be submitted, together, at the upcoming IJSBA Board of Directors meeting for voting. If you have questions or comments about this posting, please email: [email protected].

Following are the suggested rule changes and Managing Director recommendations (in bold):

  1. IJSBA will modify the promoter participation exclusion. This will allow promoters, and their children, to participate in IJSBA Sanctioned events. IJSBA will require that there is a backup race director for the entire event if it is the promoter participating and that this designated race director will be the active director anytime a promoter or a promoter’s family is in a heat and this substitute director will take over if the promoter becomes incapacitated or unavailable to continue to the race management for the event. The race director decisions for any heat/class/etc. where the promoter participates are appealable to IJSBA for review.
    Recommendation: Yes, IJSBA should remove the promoter participation exclusion where proper safeguards and reviews can be implemented.
  2. IJSBA will work with the homologated hull manufacturers to changes to allowances in aftermarket hull provisions. This includes approaching such topics such as lengths, lengths of pumps, handling features on the upper deck, etc.
    Recommendation: IJSBA will convene a series of meetings with representatives from each manufacturer of homologated aftermarket hulls to carry this subject further. The focus of discussion for 2025 will be upper deck features which affect handling and stability. Many of these features are currently being described as “splash guards” or hoods. The features should be normalized for what they are doing and for the handling and stability needs of the aftermarket units.
  3. Shall IJSBA redefine any parameters of the intake grate for use in Freestyle competition:
    Recommendation: IJSBA should clarify, where necessary, that a minimum intake grate is required for freestyle Competition.
  4. Shall IJSBA remove the requirement for a restrictor plate for 1500cc based Ski in Junior classes?
    Recommendation: No, IJSBA should not remove this requirement. The displacement to weight ratio of an SXR 1500 is higher than an 1100 Stock/Rec Lites Runabout. IJSBA has previously determined that this ratio is outside of a parameter that is appropriate for Junior category racing. Very little support was received for the removal of restrictor plates.
  5. Shall IJSBA clarify, restrict, or expand any provisions for swapping of OEM camshafts between OEM units?
    Recommendation: No. The only conceivable way to accurately regulate the swapping of OEM camshafts between OEM unit would require a graph chart that would be monotonous to create and complicate the tech inspection process. For more than a decade, engine bases have not changed and most models of a watercraft are a reoffering of a previous watercraft with a slight horsepower improvement accompanied by minimal cosmetic changes. Trying to determine a cut off point of where one OEM camshaft can and cannot be replaced by another OEM crankshaft promises to be a lot of work trying to tackle a nearly unsolvable problem and where the problem can be solved it will be extremely challenging to implement. Small gains by matching specific year OEM camshafts to specific OEM engines of mismatched years may be something that we just have to tolerate.
  6. Shall IJSBA clarify whether additional tubing and ventilation is allowed or not, in addition to the OEM ventilation tubes?
    Recommendation: Yes. IJSBA should revisit the wording for possible clarification to ensure that competitors are aware of limitations on changing ventilation where allowed.
  7. Shall IJSBA restrict aftermarket impellers to single type impellers instead of allowing for dual type impellers?
    Recommendation: No, there was insufficient support received for this suggestion to justify consideration. The installed base of dual impellers is extremely high and this type impeller is a costly investment in performance. To remove this allowance would require extensive research and notice of at least one year before implementing
  8. Shall IJSBA publish the Formula Naturally Aspirated rules as a specific class set of rules?
    Recommendation: Yes.
  9. Shall IJSBA remove boost limits in Ski GP?
    Recommendation: Boost limits should not be removed as this would allow for uncontrolled speeds on the race course and unleash heavy cost potentials. Boost should be raised 1psi to be consistent with springs typically found in the type of boost controllers currently mandated by IJSBA.
  10. Shall IJSBA allow electronic boost control as an alternative to mechanical boost control?
    Recommendation: With the support received by the public, it seems this is a pathway that IJSBA needs to travel. However, there is insufficient information as to exactly what electronic boost control to use. The current state of things would seem to require that a fixed electronic device could be used or, in the absence, a datalogger (provided by competitors) which would be checkable by technical inspectors which would result in instant disqualification if the data showed higher than allowed. This provision must be further developed.
  11. Shall IJSBA change Runabout 1100 Open to Runabout 1100 GP?
    Recommendation: No. There is already a Runabout GP class for competitors who want extreme speed and expensive exotic modifications. 1100 Open costs are reasonably controlled and allow a mid point for extreme runabout performance without uncontrolled speeds and costs. This class should be preserved.
  12. Shall IJSBA eliminate Expert Ski GP and replace the category with Expert Ski Modified instead of running both classes?
    Recommendation: No. These classes should both be allowed. Expert Ski GP allows a preparation point for a pathway to Pro Ski GP and allows development of riding skills in a premium performance class. There are a significant amount of competitors who would have to abandon their GP built Ski or go into Pro Classes where they may not yet be ready. Expert Ski Modified can stand alone as an alternative.
  13. Shall IJSBA clarify Stock and Modified rules to specifically allow for timing gears to be installed on camshafts?
    Recommendation: Yes. Timing changes are allowed. IJSBA’s interpretation of this rule allows for the timing gears to be used. Therefore, it should be specified in the rule book.
  14. Shall IJSBA allow aftermarket fuel tanks in Ski Modified class?
    Recommendation: IJSBA should prefer the use of OEM tanks from homologated watercraft. IJSBA could leave open the opportunity for thoroughly vetted fuel tanks USCG/UL/UE approved.
  15. Shall IJSBA allow for any aftermarket pump to be used in Ski Modified?
    Recommendation: No. There have been no pump companies requesting to be included as an approved pump which has been rejected. IJSBA should continue to limit pumps to ensure cost controls for Modified Class [Note: this was erroneously posted as a fuel pump answer from older notes and has now been corrected.]
  16. Shall IJSBA change Rules VSK 2.2 to allow modifications to the bottom of the ski, as long as it stays within the original length (front to back) and width (left to right)?
    Recommendation: No. IJSBA should continue to require OEM bottoms for Vintage Ski. This restriction controls costs, keeps the intention of Vintage Ski goals, and will help maintain conservative evolution of further upper deck modifications are allowed. Vintage Ski competitors risk splitting this class between a Modified/Limited or similar spit of further exotic modifications are allowed.
  17. Shall IJSBA change the wording of Vintage Ski Rule SK 2.4 to allow for one set of traditional sponsons and one set of tubbies indicating left and right of each system?
    Recommendation: No. This allowance would be a further departure from the goal of Vintage Ski which is showcasing the traditional power, handling, and style of the historic watercraft which gave birth to our sport. The purpose of this class is not to have modern handling aftermarket ski that look like historic ski watercraft. Vintage Ski competitors risk splitting this class between a Modified/Limited or similar spit of further exotic modifications are allowed.
  18. Shall IJSBA change wording in Vintage Ski Rules VSK 4.3 and VSK 5.2. VSK 4.3 to eliminate conflicts for signals pertaining to CDI and fuel injections?
    Recommendation: Possibly. This requires further research with technical inspectors in regions where decisions are being made about CDI and fuel injection where current wording is causing conflict.
  19. Shall IJSBA change wording in Vintage Ski Rule VSK 6.1. to allow for titanium?
    Recommendation: Yes. Public input supported this recommendation. [Managing Director’s comment: I am personally against it for cost control reasons but if this is what the Vintage Ski community thinks is best then spend away Vintage racers!!!!].
  20. Shall IJSBA clarify Vintage Ski Rule VSK 6.1 is regarding ‘the overall length of a complete pump and nozzle assembly. This is to account for the fact 750 pumps don’t have a shoe as part of the assembly while the 550 does. The rule clarification is for the allowance of additional length compared to the stock length of the “complete pump assembly.”
    Recommendation: Yes. Public input supported easier allowances to use the 750 pumps and this change seems necessary for the allowance.
  21. Shall IJSBA allow Sea-Doo 1998 XP (a.k.a. XPL Hull) watercraft to utilize an aftermarket hood in Limited Classes where Two Stroke Runabout are allowed?
    Recommendation: No. Public comment was mostly against this. Furthermore, this is not a like for like comparison for the same allowance for X4 hulls. Where aftermarket hoods were allowed for X4 hulls, the weight savings was negligible in comparison to the cost and difficulty of obtaining used OEM hoods. In the case of an XPL style hood, the weight savings is so significant that an aftermarket hood would provide the same advantage of a lightweight hull.
  22. Shall IJSBA mandate what brand and models of the device to use for checking boost pressure so everyone will have the same reading in Ski GP, and Sport GP classes?
    Recommendation: Yes. IJSBA needs to ensure systemic normalization between events and mandating as much equipment as possible will remove uncertainties and reduce conflicts as competitor go from event to event produced by different organizers.
  23. Shall IJSBA print clarification in the Runabout Superstock Class to clearly and specifically indicate the allowance aftermarket rods and pistons?
    Recommendation: Yes. These modifications were allowed. If wording needs to be changed to make that more clear then IJSBA should do that.
  24. Shall IJSBA implement the impede of progress rule as presented online?
    Recommendation: Yes. However, rather than this be a specific rule which is difficult to make as a uniformed rule, IJSBA should create a “Race Director Guide” viewable by the public which would include this concept as well as others in an effort to publish guidelines on how some penalty calls are made.

2025 Boat Show Season Underway

0

The 2025 Boat Show season officially kicked off yesterday, Jan. 8, with the opening of both the Chicago and New England Boat Shows starting their five-day run that will end on Jan. 12. The Atlanta and Charlotte County Boat Shows crank up today and will also run through Jan 12, with the Oklahoma and Daytona Shows rounding out the week with two-day schedules on Jan. 10-12.

With more than 35 high-profile shows listed on major event calendars, plus regional and dealer boat shows scattered across the country and, indeed, throughout the world, the coming weeks offer ample opportunity for PWC riders – whether newbies or pros, racers or recreational riders, or anything in between – to check out the 2025 PWC models, accessories, marine electronics and equipment.

2025 Mark Hahn Memorial 300 Registration Now Open

0

While the bitter cold (or chilly weather, for those less dramatic!) and frigid winds continue to sweep across many parts of the country today, a bit of warmth and anticipation snuck in when the announcement was made yesterday that registration for The 2025 Mark Hahn Memorial Havasu 300 is now open.

As posted on the race’s Facebook page, the 21st Annual Mark Hahn Memorial Havasu 300 will be held on Feb. 22 at Point Beach, Lake Havasu State Park, Lake Havasu, Arizona.

First, some bad news … the post, published less than 24 hours ago, mentioned that priority pit spaces were “limited.” It seems a number of people took that notification seriously, because when WCJ checked the registration page at 11:55 p.m. on Jan. 7, Priority Pit spots appeared to be sold out.

However, you can still select the option to have your name put on the Priority Pit waiting list for One (1) priority spot (for Vehicle & Trailer ONLY!!!)

As noted in the announcement, The 21st Annual Anderson Powersports IJSBA Mark Hahn Memorial Havasu 300, presented by Hot Products, RIVA, Jettrim, Ford Bros. Racing, Impros, Works H20 Designs, SBT and Monster Watercraft, will use a new GPS-based scoring program that has been proven successful in P1 and other endurance racing applications. With this program, each team can monitor their position within the race in real-time. The only caveat is that the program only assesses penalties after the race has ended, so any penalties assessed during the race will be put in once the race has concluded, affecting the final order/scoring.

“We have done a lot of research to bring a program that has proven successful in racing,” assured race officials.

It is also noted that Pre-registration closes at 11:59 pm PST, February 1. Entries received after that time will be assessed a $100 late fee.

Also, IJSBA membership is required to participate in the race. For those that do not have a current IJSBA membership, a membership must be purchased online or at the race site in order to enter the race.

Stay tuned to WCJ for more information about the iconic race in the coming days.

Also, the announcement of registration opening for the Havasu 300 was compelling enough to postpone the story we were already working on for today, but it is still worth noting that today, Jan 8, is officially the start of the 2025 Boat Show Season.

While there may have been a regional boat show that already slipped by (who knew there were SO many boat shows!), for the most part, and by most commonly-recognized boat show calendars, today, Jan. 8, begins the 2025 Boat Show season, with the Chicago and New England Boat Shows running from Jan. 8 – 12, the Atlanta and Charlotte County Boat Shows crank up a day later and running from Jan. 9 – 12, and the Oklahoma and Daytona Shows rounding out the week with two-day schedules on Jan. 10-12. 

Stay tuned to The Watercraft Journal for tomorrow’s delayed article on the 2025 Boat Show season.

GreenHulk Starts Off 2025 With New & Updated Products For Sea-Doo, Yamaha

0

New and improved – while the advertising slogan may be trite, the words take on some serious impact when the one throwing them out there is GreenHulk PWC Performance

Almost before the New Years fireworks had faded, GreenHulk was rolling out news to keep PWC fans warm at heart, even if their fingers are frozen by January’s uncooperative cold weather.

GreenHulk has announced two new products already, both for 2025 model skis – one for Sea-Doo’s 2025 GTX Limited 325 and one for the 2025 Yamaha JetBlaster.

For the JetBlaster, the Pro-Series Sponsons will dramatically improve handling, with superior fin & backing plate design and a bulletproof mounting system that features billet aluminum backing plates and four anchor points with aluminum inserts in sponson fins. The mounting plate angle and sponson fin depth are adjustable to control the amount of influence they have on the craft, and they are IJSBA-legal for all classes. 

Easy installation uses original mounting studs and purchase includes all necessary hardware and installation instructions.  Priced at $489.95, but use code “greenhulk at checkout for a $49 discount. 

For Sea-Doo, RIVA’s new Sea-Doo 2025 GTX Limited 325 iDF Delete Kit is now available from GreenHulk, on sale for $1,400.84, down from a regular pricing of $1,474.57

As noted by The Watercraft Journal in late 2023 when RIVA released the iDF Delete Kits for 2022-23 RXT-X and 2022-24 GTX models with iDF, Sea-Doo’s Intelligent Debris Free system (iDF) is a set of gears in the engine that can reverse the rotation of the impeller, reversing the water flow so debris is blown out, eliminating the need to manually removing debris from the intake.

As handy as that feature is for recreational users, the system has become known for early failure on high-performance watercraft operated at 8,400 rpm and above, and has a tendency to negatively impact performance and limit modifications.

Meant primarily for race skiers and those who wish to tune their skis for speeds in the upper 80s – and above – this kit directly replaces your ski’s iDF system. 

In an earlier interview, RIVA’s Mike Hodges told The Watercraft Journal, “Since BRP updated the iDF internals, we’ve found that the failure rate is pretty much a non-issue on stock craft as well as craft modified up to Stage 2. However, we’ve received reports of a few iDF failures on modified craft run above 8,400rpm, which is well beyond the system’s intended use.”

RIVA’s iDF-removal kit uses all OEM engine & driveline components, and instructions directly out of the Sea-Doo shop manual, to eliminate the iDF system and return the ski to one-way only driveshaft rotational operation for improved reliability.

“In addition to improved reliability we found that overall performance is improved by what we believe is a reduction in mechanical drag related to the iDF gearbox components,” Hodges said.

While the process does require “deactivating” the iDF function through BRP Dealer Diagnostic System (BUDS) or Maptuner X with Tuning License, and requires a high-level mechanical proficiency and specialized tools to complete, use of this kit will enable performance modifications beyond RIVA Stage 2, as well as that reduction of mechanical drag on the driveline caused by iDF gearbox components, resulting in increased performance.

 Specialized tools required include: PTO Sleeve Remover/Installer ($86.99), Water Pump Impeller Tool ($28.09), Crankshaft Locking Tool ($57.99), Driveshaft C-clip Remover ($154.89), Water Pump Shaft Tool ($30.89) and Oetiker Pliers ($47.00) 

While not “new” (and technically announced before the new year, with the release posted on Dec. 30), GreenHulk’s popular and well-proven Victory Turbo Kit for Sea-Doo Spark/Trixx – is now in it’s third revision – with even better durability and smoother installation combined with black powder coated parts for outstanding look. 

See the full data from the original post below:

This is a complete engine hardware kit and includes all parts you need to convert your Sea-doo Spark/Trixx and turn it into a turbocharged performance machine! We highly-recommend you replace the impeller with a Solas 13/18 (not included in this kit). You will also need to flash your ECU with a new tuning software especially designed for Sea-doo Spark/Trixx with this turbo kit. The flash (programming) is fast and effortless with our tuning software and the MaptunerX which also brings more useful features for the Sea-Doo Spark.

The Watercraft Journal’s Most Popular Articles of 2024

0

With a fresh new year ahead of us, The Watercraft Journal is following tradition to skim back through the pages of the past 12 months and see what motivated, inspired, interested and engaged our readers. 

Reviewing the numbers gleaned from year-end reports from our year of publishing The Watercraft Journal to find out which articles worked – and which ones fell flat – helps focus WCJ attention on what most of you honestly care about. And it continues to be clear that what most of you care about is reveals of highly-anticipated new watercraft, insightful reviews on the latest production vehicles, and the latest gossip on potential future watercraft.

While PWC race-based articles continue to hold a strong core of regular readers, racing coverage again failed to make it to the top of the heap, despite some definitely intense debates over rules, sanctioning bodies, and what the future of PWC racing holds. 

While annual brand name lineups again held the lion’s share of our readers’ interest, it was honor, respect and  sorrow for the loss of Tyron Motzouris – and support for his brother Dustin, his wife Dominique and his children and extended family that pegged our farewell article as one of the most important of the year. 

In addition, our continuation of the daily Look Back feature, highlighting articles from previous years, has renewed significant interest in several past topics, and we have added a special section to our “Top Articles of the Year” feature to highlight those hot flashbacks.

Now, without further ado – the top WCJ stories of 2024!

Sliding into the last spot on our list, the June 5 Kawasaki reveal, Gallery: Kawasaki Rolls Out 2025 Ultra Lineup, New Colors, Pricing & Introduces Angler JetSki. While Kawasaki’s release of the 2024 stripped-down, frills-free Ultra 310X hot rod, this year in Ebony/Neon Red, priced at $19,199, and the Ultra 310LX-S returning decked out in Ebony/Lime Green for $20,199 drew some interest, it was the new 160LX-S Angler JetSki that ratcheted up interest, both online and on dealership floors. 

As noted at the time by WCJ Managing Editor Kevin Shaw, “the Angler is possibly one of the most surprising – yet, smartly timed – new entries to the rapidly-growing JetSki lineup.”

Marketed with the tagline, “Catch The Good Times” (a play on Kawasaki’s long time “Let The Good Times Roll” maxim), the Angler packaging included a 7-inch UHD2 7cv Garmin Echomap Navigation (Fish Finder Chartplotter) occupying the right-hand rearview mirror. Pages of navigation, seafloor mapping and tide/current charts are quickly and easily accessible through the full color screen. Other features included the 1,498cc in-line four-cylinder marine engine, 22.5 degree deep-v hull to assist in rough-water handling, Kawasaki Smart Reverse with Deceleration, and side floats for added stability while fishing. 

Next on the list was the March 12 edition of Vicious Rumors & Vile Gossip: Leaked Patents Reveal The Most Advanced Kawasaki JetSkis Ever (Video). Sticking with the early green theme of the 2024 year, WCJ’s  discovery that Kawasaki’s legal department had filed not one, not two but 22 patents for new designs, innovations and technologies for future JetSkis ramped up even more interest in the brand. 

The patent filing gave a clear roadsign of the direction of Kawasaki’s design and feature path, with 3-way adjustable seat design, gullwing doors, multimount handlebars and rear storage track system exclusive to the Ultra Deck, the Jetsounds 4S stereo system, LED running lights being incorporated into the front bumper, and the overall aesthetic of both the redesigned Ultra and STX JetSkis, respectively. But the news that the brand is now working on a self-driving JetSki – a watercraft that can be operated without a rider by using a low-speed battery-powered electric drive-and-control system [a secondary propulsion system to the internal combustion engine – probably played an even larger part in the popularity of this article. 

Almost garnering equal interest from WCJ readers, the next two entries on the 2024 Top Articles list –  WCJ coverage Intrdoucing the 2025 Sea-Doo Lineup and Introducing the 2025 Yamaha WaveRunner Lineup – highlight the fact that Manufacturer priorities, decisions and innovation remain a driving interest in the PWC Community.

First up was the Aug. 12 Yamaha reveal, with a letdown SVHO that failed to answer Sea-Doo’s 325-horsepower benchmark while the FX and GP received updated Connext infotainment centers and revamped speaker systems, and the EX line morphed into a fully redesigned, lighter, more nimble Rec Lite series – six 2 and 3-up WaveRunners branded Jet Blaster – to fill the entry-level void.  

On the Sea-Doo side, WCJ’s Aug. 20 reveal showed that Sea-Doo was headed in an entirely different direction than the one taken by Yamaha. While Yamaha’s focus was trimmed down Rec Lites, Yamaha doubled down on their sport fishing focus, both in the way of a newly re-themed Switch tritoon wholly outfitted for all-day fishing excursions and a tippy-top-of-the-line Sea-Doo Fish Pro Apex – a model even more equipped than the Trophy.

In addition, Sea-Doo’s most luxurious runabout, the GTX Limited, now comes equipped with both the wild 325-horsepower 1630 ACE introduced last year exclusively to the X-models as well as the hydraulically-damped steering system and a gorgeous 10.25-inch wide LCD touchscreen dashboard.

Settling in at the top of the model-based articles of 2024 was an in-depth review and gallery of the 2025 Kawasaki Ultra 160LX-S Angler JetSki, with a focus on the model’s superiority in offshore and rough water, thanks to the Ultra platform. The Ultra’s 22.5-degree deadrise and true Deep-V hull permits the JetSki to track smoothly through cresting 5-footers at speed without nose-plowing, erratic bow hunting or unhooking the pump. Above 15-20mph, the Ultra can sluice through chop unlike any ST3-based Sea-Doo.

And while Manufacturer reveals and model reviews were clearly a key interest for readers this past year, there was no doubt that WCJ’s Farewell To Tyron Motzouris drew those from the PWC family – both inside and outside the competition arena – to the website and WCJ’s social media feeds to remember, share stories, offer support to the extended Motzouris family, and pay tribute to one of the most innovative – and most kind – members of the PWC community. 

And that rounds out our list of the most-read, most visited articles of 2024. As mentioned earlier, our daily  Looking Back feature continues to draw readers back to old articles, sometimes even outperforming that day’s feature articles. During the past 12 months, the top re-visited articles from earlier years were:

2025 Race Season Shaping Up As Promoters Release Schedules

Photo: WatersEdgePhotography

The 2024 PWC Race season had its usual share of spectacular performances, startling upsets, surprise endings and awe-inspiring comebacks. It also had more than its share of drama. 

As with many dramas, the only thing to do is sit back and see how they play out, and with PWC racing – or any competitive arena – the majority of participants stay out of the fray, caring only about how any conflict resolution impacts their season – where and when the races are, the purses available, and the rules they have to follow to win said prize money. 

In the past week, the PWC race family is starting to see progress on at least part of those priorities – the when and where – as several promoters have released 2025 season competition schedules. Although there are still some holes to fill – with several TBD notations in the lineup and several promoters not yet releasing 2025 information – there is enough meat on the bone to fire up some enthusiasm and have racers dragging out the 2025 calendar to pencil in what really matters – Race Weekends! 

Here is what we know so far, as posted by race organizations:

EAST COAST WATERCROSS
Ok racers here it is! 2025 schedule is almost finalized!

6 weekends, 12 rounds of racing and maybe even Friday practices.

We will announce more soon on Friday practice times but know that our goal is to open the course up Friday afternoons for a few hours for practice.

Class lists will come out soon, we are working on a plan to bring together some different class structures to cater to demand such as VET classes and a class to allow the two stroke Superjets with pipes to race with us so the @ajsa_racing boys can get in on region 8 bar banging!

We are waiting on paperwork from a new site in Clark PA but it looks promising that those dates will work out well, this Clark PA round is the weekend prior to the @greatlakeswatercross harbor beach cup and triple crown round and is only 5.5 hours away, both myself and @h2ox595 will be heading to race the triple crown in harbor beach after Clark round.
The first round is still waiting on permits my goal is to have it in my hometown area of central NH, more to come on that as we make progress.

Plattsburgh NY will host the third and final round of the triple crown series where we will be handing out no less than $25,000 to the winners thanks to a lot of key donors and guys like @toddczarcinski behind the scenes putting in the work on this series! This site can be glass or be 4-5’ers so with any luck it’s rough and with all beach shoreline we won’t have any safety concerns with heavy winds and waves  like we had at Sylvan last round of the season last year.

We need sponsors to help us get these races pulled off on a professional level so please reach out if you can help financially in any way

We are looking to fill a few staff positions as well this season if you are interested in full time or part time course Marshaling or scoring please reach out to

Thanks and we are looking forward to an epic 2025 racing

IJSBA Releases Set Of Rule Suggestions For 2025 Rule Book

0
Photo: RonnyMac.com

Following an extended period of accepting rule change suggestions from racers, IJSBA has compiled and released a set of rule suggestions for the 2025 Competition Rule Book. This year, for the first time, the newly-created Rules Committee will play a part in the process, with the committee’s response to the suggested rule changes to be posted, and taken into consideration in the compilation of the final draft of the 2025 Rule Book.

According to the procedure set out by IJSBA, “The IJSBA Managing Director will prepare a set of recommendations for these suggestions.  This year, an ad hoc Rules Committee was created and IJSBA will post a response from this committee as well.  If you have questions or comments regarding this posting or believe you have submitted a suggestion not included, please email: [email protected].”

Photo: RonnyMac.com

The full list of suggested rule changes under consideration, as submitted by racers, is as follows, with IJSBA notations in bold:

  • Modify rule excluding promoter participation to allow for this with certain oversite features.
  • Refine Ski GP Rules to remove some references to the donor watercraft (pump length, etc.).

The way the f style rules are working as you know is that after the coral if no complain all is good .

Note: The Freestyle Corral does not prevent protests for mechanical violations or missing parts, participation in the corral only prevents protests of hull design and specifications.

On a stand up the intake grate is put there for safety and also in some case to use a loader to load the pump .

What is happening now is the many people are using only a loader plate fix on the side or not even anything as grate

To me this is a safety issue just like the lanyard


I would do away with the restricted plate in this class since none of the ones that were used at world finals this year are the same size.  the speed is about 6mph faster than the 4stroke yamaha seems to be safe . I would think another item for safety in this class would be a letter of proficient from there promoter saying that the Jr is able to control the ski at the increased speeds.


It is known that swapping out the factory camshafts from the normally aspirated VXR ski into the supercharged SVHO makes more horsepower. Some have argued that they are “OEM” and are allowed per the rules for the “Stock Runabout” class. The way I am understanding the rules, is that you could swap cams from any “SVHO” model, in this case 2014-2025 from any Yamaha ski with any model originally equipped SVHO engine. Or for SeaDoo, any 2016-2023 300 ski could use cams from any of those years. I’m not sure how the rules could be written for the use of the 230 cams for the same years, if that’s an advantage or not. I also suppose one could also make the case, per the rules, that an RXP-X couldn’t use the same cams as an RXT-X  or a GP1800R SVHO couldn’t use cams from a FX SVHO, or vice versa.

From speaking to multiple tuners (Yamaha), it’s not a direct plug-n-play swap. The addition (temporary or not) of o2 sensors, air flow meters, and tuning are necessary to get the tune “correct.” This small gain, yet still an advantage, adds a lot of cost to a “Stock” class that most racers would have to hire out to get done, making it harder to gain new racers, like myself, getting into the sport, or even retaining current racers. Adding in clarification, whether allowed or not, would help with costs and complexities associated with building a ski for the “Stock Runabout” class.

RAS.1.2 Original equipment parts may be updated or backdated to original equipment parts of the same model. The part must be a bolt-on requiring no modifications to that part or any other parts except where rules allow substitutions or modifications. Models with the same designation (i.e. RXP-X, SHVO, etc.) will generally be considered the same model unless restricted in the homologation listing (See Appendix).

RAS.3.4 Camshaft(s) must remain stock. Replacement bearings or bearing shells are allowed, providing they maintain their original type and dimensions. Camshaft timing may be changed.

  1. 2. Can the rules clarify whether additional tubing and ventilation is allowed or not, in addition to the OEM ventilation tubes?

RAS.2.13 Engine compartment ventilation tubes must remain as originally equipped.

  1. 3. Can the rules clarify whether aftermarket “keepers” can be used or not? Although the GP1800R SVHO keepers are very good on their own, I would like the option to use some aftermarket ones when I get my valve springs and retainers installed next month, and don’t won’t to have to pay for this service again if I move up classes and my tuner recommends different keepers. For the “Stock” class, I think there is zero advantage. It’s just more of a piece of mind item using “better” keepers.

RAS.3.5 Aftermarket valve springs and valve spring retainers may be used.

  1. 4. Restricting impellers to just a single impeller like OEM, not a twin impeller, which is currently allowed. It’s a major advantage having the twin impeller, but gets away from the roots as a “stock” ski and doubles the cost. Since the West Coast series runs in elevation and sea level, two impellers, if not more, are necessary. I think it would be a win-win to restrict it to just a single impeller.

RAS.10.1 Impeller may be modified or aftermarket, providing that the original diameter is maintained. Replacement wear rings that are within OEM internal diameter specifications may be used. Silicone adhesive sealant may be used in addition to original equipment seal to seal pump inlet. Visibility spout must be removed or plugged


Runabout Naturally Aspirated: add runabout naturally aspirated to the displacement guide specifically stating what the requirements are for this class. In the past, the class has been four stroke stock 1800 cc (now1900) or two stroke limited 1300 cc (aftermarket hoods are not allowed)

Runabout naturally aspirated is not in the 2024 rulebook and I was unable to find it in a few previous years. I was able to find the displacement in a previous IJSBA post (see below).

Note:  This class was, many years ago, a formula class combining Two Stroke Limited and Four Stroke Stock rules.  This definition was for a specific World Finals.  Afterwards, Mark Hahn 300 Competitors petitioned this class to be a Naturally Aspirated Class which used actual Open Rules.  If this suggestion is adopted it will appear in the Rule Book as a specific category likely called “Formula Naturally Aspirated.”


Ski GP,,,,  boost control,  remove any limits and allow electronic control.  (it’s nearly impossible to make a good test of this unless you get into the ECU of the pilot)  the real number of boot on the water is much different then the trailer test.

Runabout 1100 open ,,, change to “GP”  this will open the class up to other manufacturers, Sea Doo needs the GSX hull the spark is too small to compete with the Yamaha 

Expert Ski GP ,,,, change this class to Expert Ski Modified 

Ski Modified,,,,, clarify rules     1. cam gears 2. fuel pump with regulator , fuel tank (some hulls run other tanks then what came with the engine package originally ), exhaust collector  to be modified or aftermarket. ( some hulls do not fit the original) 

Ski 1100 Modified    Yamaha 1050 can use any exhaust manifold that is OEM by Yamaha. (Yamaha has 3 different manifolds and depending on your hull one fits for some and not others. 

Ski Modified ,  open up the pump rule  for any aftermarket pump as long as it remains OEM dia. ( many company have pumps to sale and they contribute to the sport)


Suggestion:  I suggest the following rule change: Changing VSK 2.2 to allow anyone to create and use modified top decks. Currently, there is a monopoly on who can sell “legal” top decks. This is due to wording relating to the historical approval of the ski. Opening up the rules for everyone to have a chance continues the growth and development of the class, as well as allows the riders to have another aspect of the hobby to get involved in.

Suggestion:  I suggest the following rule change: Changing VSK 2.2 to allow modifications to the bottom of the ski, as long as it stays within the original length (front to back) and width (left to right).

Suggestion : I suggest the following rule change: Changing the wording of VSK 2.4. The current wording allows that we can use a maximum of 2 sponsons. The problem is  the definition of the word ‘sponson’ is interpreted differently by the different tech personnel.  I suggest the wording be changed to “All watercraft may be equipped with a maximum of 1 set of tubbies (front sponsons) and 1 set of sponsons (rear sponsons). A set is defined as a two part system with a left and right component.” I feel that this would relieve some of the confusion that takes place regarding the rule. People tend to call the tubbies, front sponsons and subject them to the dimension requirements and maximum requirements.

Suggestion : I suggest the following rule change: Wording changes relating to VSK 4.3 and VSK 5.2. VSK 4.3 is a rule regarding fuel injection and VSK 5.2 is a rule regarding CDI ignition. The nature of adding an electronic fuel injection system requires the addition of additional sensors, like TPS, MAP, MAF, ect. Rule VSK 5.2 says that no additional sensors may be added. This creates a contradiction, which I feel will lead to friction going through tech. I suggest adding a line to the wording on VSK 4.3 to “Addition of sensors required for electronic fuel injection is allowed”.

Suggestion : I suggest the following rule change: Allowing titanium in rule VSK 6.1. Titanium was used on the top race skis from the early 1980’s to the last year of 440 superstock and 550 modified. I understand the motivation of this rule is to keep costs down, but the additional costs of using titanium drive shafts over stainless is significantly less than the cost of other modifications that are done to the motors and pumps that are somewhat necessary to have a competitive ski.

Suggestion : I suggest the following rule change: Clarifying how VSK 6.1 is measured. The rule is about ‘the overall length of a complete pump and nozzle assembly. The 750 pumps don’t have a shoe as part of the assembly while the 550 does. The rule is there is an allowance of additional length compared to the stock length of the “complete pump assembly”. If you can see the attached picture.

Note:  This suggestion was essentially made by two different parties but only posted once.


I would like to propose a rule change for the 1997 Seadoo xp be allowed to use a carbon fiber hood in limited class, the 1997xp is 95 pounds heavier than its 1996 xp counterpart, the 96xp is allowed a carbon hood in limited class

Note:  This suggestion was made by three different parties.  IJSBA received a similar amount of correspondence apparently aware that this suggestion was being made and asking to preserve the status quo.


On ski gp and sport gp class for engine below 1100 cc. engine can do forced induction but there’s limit of boost. I suggest that no electronic boost control allow need to be only mechanical boost control or manual adjustable only, so they can’t use aftermarket ecu to control awhile racing in the moto.

NOTE:  This suggestion was clarified with the submitting party who intends this this suggestion to be a preservation of the existing allowance of mechanical regulation of boost pressure.

Clarify what brand and model to use for checking boost pressure so everyone will have the same reading on Ski gp and sport gp class for boosted engine.

NOTE:  This suggestion was clarified with the submitting party who intends IJSBA Rules to update the boost pressure blow off or checking device to mandate the product(s) by name.

Runabout superstock class, please clarify if the engine allow to use aftermarket rods and pistons. Because on rule books saying aftermarket crankshaft is allow within 5% of weight.

NOTE:  Persons advocating for shorter more concise rules should take heed of what this suggestion is adressing. The Superstock Class has always allowed aftermarket connecting rods as part of the crankshaft provision (pins, bolts, bearings, too).  This will be rephrased to describe all components of a crankshaft assembly in the 2025 Publishing.


Do NOT Impede Progress of another Racer – Safety Rule

In the drawing here the merge lane corridor is separated by the (Sausage Buoy) and this would be proper set up, but the sausage buoy does not extend this long and is set back further behind the finish line.  We are adding a longer sausage buoy (an extra) to extend this corridor this year.  The arrows indicate what I enforce and are in a straight line as racers should follow a racing line that is as straight as possible and cannot move into the opposing lane.  After the sausage Buoy racing is a straight line to the merge bupy.  A Racer may not move into the other lane, inside or outside, push, block, Slow or Impede the progress of another racer, in order to gain an advantage in the safety corridor leading into the  merge buoy.

Last week, The Watercraft Journal touted some last-minute gift ideas with the final day of RIVA Motorsport’s Holiday Sale.

Don’t worry, though! If your procrastination mode was in hyper-drive, or the Season’s schedule got out of hand, and you let the Holiday Sale deadline slip by, RIVA’s got your back with some more great RIVA merchandise with prices that have been on the chopping block for their immediate follow-up End-Of-Year sale – and this time, you’ve still got a couple days to act!

A definite highlight of the RIVA End-Of-Year sale is the slashed prices on USA-made Dual Rear Exhaust Kits for the Sea-Doo RXT/GTX and RXP models, both on sale for $1,104.96, down from $1,299.95.

These automotive-design kits deliver performance and cutting-edge style while allowing for removal of the restrictive sound suppression system located between waterbox and hull exit, resulting in improved exhaust tone and improved performance due to the reduction in back pressure and restriction. In addition, the elimination of the plastic resonator – which is prone to failure during an exhaust overheat situation – and using, instead, superior-quality, heavy-duty components, improves the reliability of the exhaust system.

With a quick video showing the steps for installation of the Kits posted to the RIVA Instagram feed and the RIVA Facebook feed, RIVA announced the inclusion of these popular kits in the sale, which runs through the end of January 1, 2025. RIVA also provides a full-length walk-through video on the Dual Exhaust Systems, where you can learn more, and also hear the distinctive exhaust tone.

Kits include mandrel bent aluminum exhaust tubes that are powder coated to prevent corrosion, large billet aluminum through-hull exhaust outlets, OEM exhaust outlet block-off and high quality silicone couplers along with all necessary mounting hardware & installation instructions.

Don’t forget that RIVA also offers handy Installation Instructions for both the RXT/GTX Kit and the RXP Kit, available online so you can check out the guide and plan your installation before even purchasing the kit.

And while the Dual Exhaust kits are definitely a highlight of the End-Of-Year Sale, there are plenty of deals throughout the website, giving savings opportunities no matter what department you’re browsing.
