Kawasaki’s Eaton Twin Vortices Series (TVS) belt-driven supercharger is what The Watercraft Journal wrote, crams an “almost excessive 16.7psi at peak RPM down the Ultra 310X engine’s throat, resulting in a true 310-horsepower, producing 1,890 lbs. of thrust from its 160mm axial-flow, single stage jet pump.”
That being said, the amount of power produced by the Eaton superchargers creates a lot of wear-and-tear, meaning that maintenance is vital. So who better to guide both the expert and the novice through that upkeep than Kawi Performance (KP) owner Steve Ciervo. In the latest KP video release, that is exactly what he does, giving precise, easy to understand instructions, with his normal attention to detail and thoroughness.
Far from a quick run-through or overview, the video is an in-depth look into supercharger maintenance on the Kawasaki Ultra 300 and 310, where they guide you through the essential steps of maintaining your watercraft’s supercharger system, covering what doesn’t need replacement, what does need replacement, and when to schedule replacements and service.
Ciervo explains that the Eaton TVS is “not your standard, off-the-shelf Eaton Supercharger,” and describes the partnership between Kawasaki and Eaton to create the R-Series supercharger custom made for high RPM, and one where, for every engine revolution, the supercharger is sucking in fully twice the air it normally would.
Ciervo points out that there are many aftermarket rebuild kits for the supercharger, but said they all have one thing in common: they don’t know this specific supercharger, resulting in ill-suited kits, sometimes even including things such as bearings that you shouldn’t need to replace, or are near impossible to replace.
But not to worry! Kawi Performance has rebuild kit options: a basic rebuild kit that includes bearings that most often need to be replaced; and two Full Rebuild Kits, one with Japanese bearings, and an “economy” kit with aftermarket bearings. All of which are available on the website linked HERE.
One of the most respected outfits in the PWC World, whether you’re talking racing or retail, Broward Motorsports undoubtedly has what it takes to put riders on the water – either by way of a new (or used) ski, top-of-the-line technology, high-quality service, or all the parts, accessories and apparel you need. And they have seven ways to get it to you – namely, 
While the renowned BMS reputation for quality and customer service links all the company’s operations, each site has their own focus and identity, and their own specials and sales, and today, The Watercraft Journal is going to do the legwork for you, and run a speed round through each store and highlight their specials, sales, promotions and events.

And for those who can’t make it to the Florida stores, be sure to browse the websites for each of the stores to find great prices on parts, service, new and used inventory, and more.
The choice between low quality/low cost, and high quality/high cost is a fairly common discussion in any activity that involves technology – especially a pursuit as driven by speed, power and performance as the PWC world, and that holds true for both the race side and the recreation side of the sport.
Active Jetsport
The design and placement of the Active Jetsport catch cans are geared toward efficiency and effectiveness – the catch cans are 100% filled with oil vapor condensing foam to pull as much oil from the passing air as possible; they are designed to allow quick and easy access to check/drain any collected fluids using the bottom mounted drain (or you can simply unscrew the lower half to fully inspect contents); and they are placed to allow easy service access at the front of the engine, with no need to remove top deck components just to access the catch can – and all for under $150!
While we all love finding new ways to boost our personal watercraft’s speed, performance, and agility, sometimes the most important features go overlooked. Things like basic security and theft prevention are essential to protecting your watercraft and should be the first priority for all owners.
