2021 Kawasaki Jet Ski Ultra 310LX

The Jet Ski® Ultra® 310LX personal watercraft spares no luxury. Enjoy the class-leading performance of the most powerful Jet Ski watercraft that features the fully-integrated JETSOUND® audio system. A five-position adjustable handlebar ensures a comfortable ride position for a wide range of riders while a GPS mount integrated into the handlebar pad accommodates your device of choice. And adding to it all, the 1,498cc inline, four-cylinder, supercharged engine makes the Jet Ski Ultra 310LX the undisputed king of the water.



A 1,498cc, inline 4-cylinder marine engine with supercharger and intercooler makes the Jet Ski® Ultra® 310 series the most powerful production personal watercraft in the world. The high-tech Eaton Twin Vortices Series (TVS) supercharger boosts the compact powerhouse, delivering unprecedented performance that is sure to ignite the fun. The sound and feel as the engine hits max boost pressure leave no question as to why it sets the standard for power and acceleration.



The advanced deep-V hull design is inspired by Kawasaki’s championship-winning race machines, with a 22.5-degree hull angle that allows the watercraft to penetrate swells and waves with great efficiency and less shock. Tuned sponsons help provide straight-line stability and high-grip performance in turns.



Quickly and easily adjust to any situation on the water. The Electric Trim-Control (ETC) system is an advanced feature that allows the rider to change handling characteristics. The ETC controls the angle of the jet pump nozzle to adjust the hull attitude for specific water surface conditions or riding style.
