Video: 400-Horsepower ’19 Sea-Doo RXT-X Hits 94.6MPH


In a video taken during this past July’s Hydro-Turf HydroDrag National Championships presented by RIVA Racing [an event that has refused The Watercraft Journal from covering this year – despite being the world’s most popular PWC magazine with 345,000 annual readers, Mikey – Ed.], the crew at Sun Daily achieved a major milestone for a stock ST3 hulled RXT-X.

Touting more boost than a Hellcat Challenger, this HydroDrag Spec class 2019 Sea-Doo RXT-X produces a staggering 400-supercharged-horsepower at 9360 rpm, hitting a top speed of 94.6 in mere seconds! The most amazing feat is that these numbers were all controlled via a ECU reflash from Chezzy Performance – earning them the title of “World’s Fastest ST3 Hull, Supercharged Sea-Doo RXT-X in the world.

An eagle-eyed viewer of the video below noted that the dashboard was a traditional analog cluster native to pre-2019 models. Sun Daily replied, “I had to change the gauges from 2019 to a 2018 to work with the tune on the ski due to the fact the ski is so new [that] the flash was not working correctly with the iBR or the display, and would turn off suddenly after letting off at 5K RPM; slight sacrifice but we are working out the quirks!”
