Kawasaki’s latest model jet ski, Jet Ski Ultra 300X, is the world’s most powerful production jet ski. The 300X is powered by a 1.5 liter (1,498 cc) in-line four DOHC engine that produces 300 horsepower. The personal watercraft comes with a deep V hull for stability and cornering performance.
The 300X Jet Ski has been completely redesigned for the 2011 model year. Not only is it powerful but it’s also practical with 54 gallons of storage space. The 300X comes with an all new advanced roots-type supercharger that produces large quantities of boos throughout all the rpm range for flat torque curve.
