GET ON THE WATER Suddenly, your shirt sleeves are too short. The 215 horsepower supercharged, intercooled engine is back in all its arm-stretching glory for 2007. It's still the most powerful engine in the industry, and has yet to get beat in the Musclecraft Shootout. And new for the RXP this year is a 155 horsepower engine option. Either way, you'll be digging into turns and beating your friends across the lake with no mercy. There's simply no letting up when a PWC handles like this.
