For the last few years, RIVA Racing has offered a specialty-built, Limited Edition high-horsepower, top-of-the-line performance racecraft (built in production runs of 25). This is not one of them. Rather, the 2018 RIVA Racing Sea-Doo RXT-X 350 is a true 350-horsepower machine that you can build yourself using the list of parts that RIVA Racing will have ready for simultaneous release (this coming January).
Based upon the new for 2018 ST³ hull, the supercharged and intercooled RXT-X 300 already promises to be a worthy successor to the outgoing T-X. Sure the newcomer is wider (from 48.2-inches to 49.4-inches) than its predecessor, but it’s surprisingly shorter (139.2-inches to 135.9-inches). More importantly, the ST³-based RXT-X 300 is also substantially lighter (828-pounds from 914-pounds).
The Blowsion IJSBA World Finals acts as the industry's largest gathering of watercraft racing's aftermarket companies, race sponsors, and pro racers. In that way, the World Finals is our sport's largest trade show. It is here that consumers and racers alike can check out new 2019 parts, apparel, custom builds, and all things watercraft for next year. This is also a good time where competitors can catch up with all of their sponsors or potential new ones.
With much of the powertrain direct carry-overs from the previous generation RXT-X 300, a large portion of the performance products already tested and developed by RIVA remained applicable.
For their one-of-one RXT-X 350, RIVA managed to push the Sea-Doo’s stock top speed of 68mph at 7,500rpm to a blistering 85mph at 8,500rpm (and that was conducted with 1/3 tank of fuel, trim set at neutral, sea level elevation, air temp 80-degrees F, states RIVA).
“Like the Spark,” Bamdas added, “The new RXT-X 300 has OEM sensors fixed in the air box. In designing a new RIVA Sea-Doo 2018 RXT/GTX 300 Power Filter (PT# RS13120), we developed a really nice stainless steel bracket that relocates those sensors.” The 350 build employed aRIVA MaptunerX BRP Bundle (All except SPARK) (PT# RS110SC-B) to reflash the ECU, a RIVA Sea-Doo 2018 RXT/GTX Catch Can/Engine Breather Kit (PT# RS19050-BCC-2), and a RIVA Sea-Doo RXP/RXT 300 GEN-4 Power Cooler (PT# RS1753-PC-I).

Developing a new exhaust system proved slightly tricky. Bamdas illustrated, “If you look closely at the hull, you’d see a pronounced step at the rear. We couldn’t drill a hole for our regular round exhaust outlet, so we had to come up with something different.” What RIVA created was a rectangular port specially CNC-machined for the new RIVA Sea-Doo RXT-X 300 Rear Exhaust Kit (PT# RS15120) that is fed by a RIVA Water Box RXP/RXT 300 (PT# RS16141). Explaining further, Bamdas emphasized, “Once you remove the plate (engine cover), there’s a lot of access to the engine compartment. It’s really nice.”
