It’s hard to believe that the prime riding months are drawing to a close in Australia as the first big group rides and professional races of the year are kicking off here in the States. Alas, that is the way of living on opposing sides of the equator. As the mercury slowly descends down the thermometer, our fellow personal watercraft enthusiasts are preparing to winterize their jet skis, while others are only starting the beginning of their winter-long project builds. That is, if they’re not choosing to brave the chill and ride anyways.

Recently, we reviewed a build that Melbourne, Australia’s Diptech Performance were installing true 300-horsepower packages on customers’ supercharged Sea-Doos. The package consisted of RIVA Racing’s a reflashed ECU, an open-element cold air intake, through-hull exhaust with a high-flow waterbox, bigger injectors, valve spring retainers, and a “boost-boosting” supercharger rebuild kit. And is with all things, you gotta pay to play – the kit starts at $4,000 and goes up from there.

Earlier this year, one very satisfied customer joined a friend to test out their recently tuned Sea-Doo RXT-X 260…well, 300 off of St. Kilda Beach. The two were met with “average conditions,” that flattened out to absolutely zero wind and perfect conditions to “test a few new mods.” Now for those looking to ramp up their DipTech 300HP package a bit further, you’ll need one of Diptech’s specially-ordered Solas props.
