The downside to building something that likes to go fast is that you also discover the weakest links in the proverbial chain. For those guys pushing their high performance 1.8-liter and now 1.9-liter Yamaha WaveRunners to the next level, they know all too well that driveline vibration is a killer.
That’s why RIVA Racing just dropped a genius innovation to help keep your big horsepower powerplants together – a Billet Driveline Coupler. Each coupler is precision-machined and powder coated here in the USA, then exactingly balanced to reduce driveline vibration all by employing the OEM Kawasaki damper which, according to RIVA Racing, “has proven much more reliable for high-performance applications.”
By using the rubberized Kawasaki damper, the coupler absorbs excessive driveline vibrations that wreak havoc on sensitive bearings and machined components with tight tolerances – particularly for those racing highly modified watercraft in offshore conditions, just like the official RIVA Racing Team did all last season.
With improved reliability stemming from its CNC-machined 6061 billet aluminum construction, RIVA’s Billet Driveline Coupler comes anodized against corrosion, and includes an O-ring sealed crankshaft cap and OEM Kawasaki Dampener (part# 92161-3797). Don’t risk premature wear and tear on your hot rodded Yamaha this year. Grab your Billet Driveline Coupler ($399.95) at RIVA Racing today.
Nothin’ wrong with a little dirty fun – as long as you clean up nice!
Hey now, we’re talking skis here!
It might seem counter-intuitive – after all, PWC is a water-based activity – one would think that it would be a self-cleaning sport. But anyone that has ever trailered their ski to the nearest lake, much less a race four states away, knows the amount of dirt and grime that can accumulate in just a few short miles, not to mention the oils and who knows what else splashed up from truck and trailer tires on dirty asphalt and the smudgey fingerprints from that kid at the last gas station (there’s always one).
Add in being strafed by a passing flock of seagulls (not the ones that ran so far away), the soda you spilled as you were locking down the ratchet straps before the trip, and the tree sap from the last boat ramp parking spot you lingered at, and you’ve got a mess to deal with. And that’s before you even peek in the engine bay where oils, fuel, grease, additives and more collect.
And of course, if you’re a surf rider, you’re also dealing with salt, and its damaging effects, both externally and internally. Even flatwater riders know that the water they’re motoring through is often anything but crystal clear.
Right about here is where Brisbane Kawasaki comes to the rescue with decades of hands-on experience in countering the grime, grunge and detritus of PWC sports and recreation, they have come up with two top-of-the-line products to help you keep your fun, clean!
First, the Foaming Shampoo & Salt Remover with the efficient and effective Foaming Gun takes care of your ski’s outside and engine bay quickly, effortlessly and safely for both ski and environment. Then the Foaming Flush & Salt Remover with Mixer adapter removes salt and calcium deposits, descales the engine cooling system, and breaks down built up deposits. Available separately for $24 each, or as a package for $109 that includes the mixing adapter and foaming gun, the price is well worth it, and the Ultimate package is a steal of a deal, with two bottles of Foaming Shampoo & Salt Remover and two bottles of Foaming Flush and Salt Remover, plus the Foaming Gun and the Mixer adapter, all for $157, including tax.
Read more about the products and process in the full press release below, and be sure to check out all the other great PWC products on the Brisbane Kawasaki website.

True to The Watercraft Journal’s reporting back in June of last year, Yamaha Motor Corp. USA pushes forward on its goal of carbon neutrality by 2030. As outlined in the company’s 2050 Environmental Plan, Yamaha marches forward toward radically re-imagining its marine offerings – this time by joining the Fuel Cell & Hydrogen Energy Association (FCHEA) as well as announcing the development of a hydrogen outboard motor.
Now before you think, “Hydrogen? You gotta be kidding me!” understand that many of the world’s biggest automakers – General Motors, Toyota, Ford, Honda, Mercedes-Benz and several others – have all invested tens of millions into countering the highly politicized EV market by developing hydrogen-powered engines. Yamaha’s involvement in such an effort is squarely on par with manufacturers looking for clean alternatives to electric-only vehicles.
It was revealed earlier that Yamaha’s efforts to reduce its environmental impact would include removing a quart of oil used in all 1.9-liter High Output Marine engines, ironically exasperating the very issue plaguing the current HO and SVHO engines – oil starvation due to an inferior oil pickup and oil pan cage/trap design (as revealed during an episode of The Watercraft Journal IRL podcast in late 2023). The prototype hydrogen-powered outboard is set to debut at the Miami International Boat Show this coming February 14-18, 2024.
Read the whole press release below: Yamaha Motor Corporation, U.S.A. joined the Fuel Cell & Hydrogen Energy Association (FCHEA) alongside hydrogen producers, infrastructure providers, engineering firms, and other off-takers as part of its pursuit of multiple technology solutions to achieve carbon neutrality.
The company recently announced the development of a prototype hydrogen outboard motor that will be on display at the 2024 Miami International Boat Show.
“Yamaha plans to work diligently with FCHEA to advance hydrogen energy and fuel cell policies,” said Martin Peters, Director of Yamaha Marine External Affairs, who will serve on the organization’s board of directors. “There is much to be done to prepare the future of decarbonizing the recreational boating and outdoor space, technically and in legislation and policy. We look forward to working as a team with FCHEA and its member companies. We hope others in our industry will join us.”
“We are very excited to welcome Yamaha to the association,” said Frank Wolak, FCHEA President and CEO. “Having an innovative company with a strong foundation in multiple mobility sectors focus on hydrogen is a tremendous asset for FCHEA and the hydrogen industry at large.”
A recent, first-of-its-kind study commissioned by the International Council of Marine Industry Associations (ICOMIA) entitled The Pathways to Decarbonisation for the Recreational Marine Industry, validates Yamaha’s approach to carbon neutrality, revealing a multi-plan approach is the best way to continue the decarbonization of recreational boating.
Through the study, a leading global engineering consulting firm, Ricardo plc, investigated propulsion technologies across nine common recreational watercraft to compare the impact of lifetime global greenhouse gas (GHG) emissions, financial costs, usability, performance, range, and infrastructure implications.
Due to the unique water environment of boats, the study found there is no “one-size-fits-all” solution, and instead recommends a portfolio of technologies to continue the reduction of carbon emissions within the recreational boating industry including a combination of electric, hybrid, sustainable fuel and internal combustion applications.
In the last two decades, the U.S. recreational marine industry alone has decreased marine engine emissions by more than 90 percent and increased fuel efficiency by more than 40 percent.
The phrase “house calls” could easily be called an archaic term in the medical profession; in 2024, it is unlikely that the vast majority of people in the United States have ever experienced a doctor visiting their home to provide treatment.
Even in international terms, physicians who pack their goods into the iconic black snap-shut doctor’s satchel and bring healthcare to their patients where they live, is quickly becoming a thing of the past.
But in rural locations throughout the world, and especially in remote locations that make a doctor’s appointment more akin to a journey as opposed to a quick trip to town, local doctors like Dr. Keigo Yasukawa still makes house calls. Yasukawa just does it with a twist, or actually a squeeze … of the throttle, that is.
Yasukawa, a native of Japan’s Miyakojima island – about 200 miles due east of the northern tip of Taiwan – now operates the Dr. GON clinic on Miyakojima. But many of his patients, quite a few of whom are elderly, live on even more remote parts of the island or even reside on nearby islands.
So several times a week, Yasukawa packs up the tools of his trade, loops a lanyard around his wrist, hits the start button on his PWC, and navigates the swells of the Pacific Ocean to make house calls.
Not content with even that level of dedication to his patients and his community, Yzsukawa began hiring other doctors, who also visit the remote neighboring islands to provide essential medical services.
You can read more about Yasukawa and the Dr. GON Clinic here and here, and learn more about the Jet Ski Doctor here.
Running for another year under Title Sponsor LIQUI-MOLY, and with the support of presenting sponsor JetTrim, Pro Watercross recently announced the schedule for the 2024 Season.
Tagged the ‘Triple Crown’ tour, Pro Watercross’ 2024 season has been culled to three tour stops – down from the more common roster of 5 – 7 stops that Pro Watercross frontman AJ Handler typically packs into a schedule. The lineup also deviates from the tour’s typical mix of surf and lake stops – this year, the competition is fully flat-water, with no surf races scheduled.
First up on the Pro Watercross 2024 season is a stop at Sebring Florida on May 4-5. With a typically technical course required by the shallow waters and the load-in ramp in the middle of the course, the Sebring race has given racers some new twists and some great races since it’s first appearance on the Pro Watercross schedule in 2021.
Pro Watercross’ second stop in their trimmed-down season is a June 15-16 race weekend at Lake Geneva in Keystone Heights, Florida – the site’s second year on the PWC Tour.
For the final regular-season stop on the 2024 schedule, Pro Watercross returns to Lake Hartwell. A long-time favorite stop for racers, and a popular event for locals, the Lake Hartwell race was dropped from last year’s tour, but returns this year – although significantly later than the usual June slot. This year, Pro Watercross will pull into the Mega Ramp at Tugaloo State Park on Lake Hartwell in Georgia for an August 3-4 race. As this race is just minutes from this editor’s doorstep, I’m hoping to see good turnout, despite what appears to be some scheduling conflicts among tours!
Although there is no mention of Arizona in the season schedule press release, the Pro Watercross Website does list the Pro Watercross International Cup in Lake Havasu City, AZ as “TBA.”
See the full press release below, and be sure to keep up with all the 2024 PWX race season news at prowatercross.org.

On Monday, IJSBA announced that ten Sea-Doo models will now be eligible for competition for the IJSBA 2024 season, nationally and internationally.
According to a press release by IJSBA Executive Director Scott Frazier, “Bombardier Recreational Products has provided sufficient documentation to homologate the following 2024 Sea-Doo units for competition in the 2024 series: Spark, Spark Trix, GTI, GTI SE, GTX, GTX Limited, GTR, GTR-X, RXP-X, and RXT-X.”
On the same day, IJSBA announced that all 2024 Yamaha models are eligible in all IJSBA sanctioned competitions.
Frazier noted that “Competitors are reminded to carefully review IJSBA guidelines, especially HOM.1.6.”
Specifically, HOM.1.6 states “For four-stroke watercraft to be homologated for competition in the Runabout division, the watercraft must not exceed 1800cc as furnished by the manufacturer. If a Runabout, as furnished by the manufacturer, exceeds 1800cc then the maximum displacement shall be the OEM displacement plus 1mm overbore on all cylinders. The maximum displacement that may be achieved by any Runabout PWC is 2000cc.”
Frazier specified that the 2024 Yamaha VX Limited HO is furnished with an engine exceeding 1800cc, making this rule applicable to this specific model.
Models identified in the announcements are immediately eligible for competition worldwide.
Regarding Kawasaki models, in a comment on September 25 of 2023, Frazier noted that “2024 model year Personal Watercraft are generally not allowed homologation until the day after World Finals and after IJSBA has determined that 500 units have been built and are available for purchase. There is an exception where a 2024 model year unit is an exact reproduction of a previously homologated unit with allowances made for colors and aesthetic features. At this time, the only units meeting that criteria is the 2024 Yamaha SVHO and all Kawaski units that have been shipped to date. IJSBA will post any updates as we learn them in order to keep competitors fully informed.
A scroll through IJSBA’s official news releases showed no announcement of Homologated models prior to the 2023 race season; prior to the September 25 note reference above, the last official IJSBA announcement of new eligible models was posted on February 24, 2022, when IJSBA posted the following notification:
IJSBA is announcing the first update regarding homologation of 2022 models. Due to supply chain issues, IJSBA is taking a measured approach to homologation of units for competition. This update covers all models of all OEM units and is effective immediately.
Supply chain issues continue to cause severe disruption to the production and delivery of new OEM Personal Watercraft. IJSBA has been making concessions to the competition community to allow for flexibility in the repair and modification of OEM units for use in competition. These concessions will remain for the 2022 competition season. As part of balancing the needs of the community along with the obligations for ensuring uniformity, IJSBA can tentatively homologate new 2022 units and the parts and repair manuals as follows:
Kawasaki: All Kawasaki units for 2022 are either the same or substantially the same as all previously homologated models with the exception of the Ultra 310 line. Therefore, aside from the Ultra 310, all 2022 Kawasaki models are now homologated for both US and international competition and the contents of the parts catalogs and repair manuals are now included in the homologation. The Ultra 310 line, having met the minimum production numbers at the factory but having the product count diverted globally is eligible for only provisional homologation at this time. Therefore, the Ultra 310 is eligible for Open Class competition only and may not be used in any Stock Class or Limited Class categories until such time as sufficient distribution has taken place at both US and international dealerships. IJSBA will continue to monitor dealer deliveries and will provide news of complete eligibility for all categories at the appropriate time.
Sea-Doo: All Sea-Doo models for 2022 are either the same or substantially the same as earlier homologated models. Therefore, all Sea-Doo models and their corresponding parts catalogs and repair manuals are homologated for both US and international competition.
Yamaha: All Yamaha models for 2022 are either the same or substantially the same as earlier homologated models. Therefore, all Yamaha models and their corresponding parts catalogs and repair manuals are homologated for both US and international competition.
Anyone with questions about the IJSBA homologation process is asked to email [email protected].
For 2023, the winner of The Watercraft Journal’s lauded “Watercraft of The Year” award went to the 2023 Sea-Doo Explorer Pro 170.
Exhibiting unique and innovative features targeting a burgeoning market segment, the Explorer Pro bested a dozen other units to earn this accolade.
In celebration of winning the WOTY award, Sea-Doo placed the 2024 Explorer Pro 170 and its supercharged 230-horsepower sibling on display at the 2024 Discover Boating New York Boat Show held in the Javits Center on Manhattan this past weekend.
Tens of thousands of attendees visited Sea-Doo’s sprawling booth, perusing the 325-horsepower RXP-X and RXT-X and observing the podium displaying the Watercraft of The Year announcement.
Social media posts from BRP’s corporate accounts as well as that of Sea-Doo both shared the news of the Explorer Pro’s success in winning the hard-fought praise, particularly in light of this author’s rather critical review of the machine.
For those who know already, the Kawasaki Ultra JetSki remains the preferred weapon of choice for most offshore/rough water riders. It’s dramatic 22.5-degree deadrise makes its deep-V hull a wave splitter, allowing the craft to piece a swathe through chop unlike lighter or less aggressive hull designs that might skip or slide over the turbulent water’s surface.
Unfortunately, the Kawasaki’s heft and displacement hull also makes it considerably slower than its competitors. Yamahas and Sea-Doos require much less thrust to reach competitive racing speeds than the Kawasaki, so what is to be done? Kspeed has been hard at work solving said issue and not solely in getting the supercharged JetSki to produce more power.
In a recent Facebook post, Kspeed wrote the following: Final test of the production KS3 plate. Holy Moly! You’re gonna want to jump on this fast. Instant 3+mph gain even on a full tank and this has been repeated time and time again on several skis in a multitude of conditions and with numerous test riders.
Goes over light chop faster, flies straighter and doesn’t lean over. Point and shoot and make going fast look like child’s play. It’s the GOAT of ride plates. You can buy it today and see it in 3D glory on our website. It will ship in April 2024.
The revised ride plate helps reduce drag, elevates the bow higher up out of the water (when used together with the 3-degree pump wedge) and gets the JetSki to planing speeds faster – all necessary in getting modern Kawasakis back into competition with the other guys’ skis. We look forward to seeing updates on the KS3 ProRace Plate as they come.
Keeping up with the sport of PWC racing can be a challenge – especially during the slow, dreary down-months of winter, with every racer – from novice to world champion – eager to get the next season rolling, and tour promoters, sanctioning bodies and race directors scrambling to lock down race sites and dates.
With the 2024 season still a “few” hard freezes, winter storms and frigid mornings away, it is shaping up to be a race-packed season, with even more race events than the 2023 season, which in and of itself was a busy year. But as much as that may be viewed as (Very) good news by both racers and fans, it also exacerbates the aforementioned challenge – keeping up with race schedules.
Luckily, thanks to the dedication of one racer, that challenge is significantly reduced.
For more than five years now, Kirsten Hasty – a Region 8 Sport and XPL racer – has managed, updated and maintained the PWC Racing Schedules Facebook page, and it is easily the most accurate, up-to-date resource for the When and Where of PWC competitions.
From the day the page launched, its purpose was clear, stated in the page description
This group was created for the sole purpose of sharing information concerning PWC Racing schedules in the US and Canada. This page will include all sanctioning bodies in the US and Canada. Announcements at the top of this page will have all known US and Canadian racing schedules and will be updated as more information becomes available. Feel free to post information about upcoming races in the US and Canada. This site is for INFORMATION related to US and Canadian race schedules only. Any post that is not information related to race schedules in the US and Canada may be deleted.
Despite the clear boundaries stated in the description, with nearly 3,000 members, one would expect a fair amount of drama on the page, especially with some of the recent shakeups in the competitive PWC status quo. One would be wrong, in this case, however; PWC Racing Schedules remains an informational clearinghouse, not a free-for-all discussion forum. There are plenty of those around, and it is refreshing to know that there is still a place to turn for a reliable, up-to-date compendium of race announcements, schedules, rules and related news, free from the debates and dissension that can dominate many PWC pages and discussions.
As PWC racer and 2020 Women’s Runabout World Champion Renee Hill stated about Hasty, “She’s pretty accurate on all the dates because she gets them right from the promoters. I used to race against her at the World Finals. Always had a smile on her face and loves PWC racing like so many of us.”
For Team Reckless Abandonment’s Ryan Stevens, the reliable information from Hasty’s Facebook page helps him put together a detailed schedule to keep himself and his daughter on track for their races.
“I absolutely love what Kirsten does for us. I am able to see the whole list of races in order; I then take that list and use ChatGPT and add distance traveled and stops needed per race, then I make up my mind what is going to work out best for me and my daughter,” he said. “Kirsten makes it easy and simple. When someone asks about racing, it is always so simple to just direct them to the page and download the file.”
Following is a simplified roundup of race dates for the 2024 season – for details and a consistently-updated source for new announcements about the coming race season – visit, like and follow the PWC Racing Schedules Facebook page – and drop a thank you in the comments to Kirsten for the countless hours she puts into keeping this resource available for the PWC family.
