The ETC controls the angle of the jet pump nozzle to adjust the hull attitude for specific water surface conditions or riding style.

Carve The Waters

  • DEEP-V HULL DESIGN: 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.

Other Features

  • Kawasaki Smart Steering, 5-position adjustable handlebar, Coupling – Direct drive from engine

Ultimate Power

  • SUPERCHARGED PERFORMANCE: 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.
