    Aggravated Assault: 2016 Sea-Doo RXT-X 300 (Video)



    How do you get a middleweight boxer to hit like a heavyweight and be as light on his feet as a featherweight? That, we presume was the challenge pinned to the board in Sea-Doo’s new product development office a few years back. The evolutionary step from last year’s RXT-X 260 to the 2016 Sea-Doo RXT-X 300 of today is far more than horsepower and deserves some further understanding.

    Well, not entirely. A large contributor to the added power is due to redesigned centrifugal supercharger that produces 30-percent more boost (18psi). A new compact wheel spins 8-percent faster at 47,000rpm. The new efficient design features twice the blades of the outgoing design (from 16 to 32) and a revised drive shaft that rides on two composite bearing packs at either end of a near inch-thick shaft, engaged by 8 steel clutch washers.

    Prior to 2016 a pure stock RXT-X260
    produces very close to 10 psi of SC boost, therefore a 30% increase would be 13 psi not 18 psi!
