Jet Ski® Ultra® 310 LX. Ebony/Candy Lime Green

JET SKI® ULTRA® 310 SERIES 310 SERIES SUPERCHARGED ENGINE Meet the single most powerful factory-built personal watercraft engine ever created: a beastly liquid-cooled, 1,498cc, in-line 4-cylinder marine engine with a roots-type TVS supercharger and intercooler. From the supercharged decals displayed prominently on the hood, to the sound and feel emitted from the 160mm jet pump as the engine hits max boost pressure, this engine is designed to deliver a thrilling experience for all five senses.

INTAKE Fed by a 60mm single throttle body, a lightweight intake manifold enhances low- and mid-range performance, while the fuel pump supplies the high-flow fuel injectors at high pressure for power and fuel efficiency. Complementing the 4-into-2-into-1 powerboat-style exhaust system, the dual water muffler offers increased volume and reduced power-robbing exhaust back pressure. SUPERCHARGER With every engine revolution, the 4-lobe rotors of the Eaton Twin Vortices (TVS) roots supercharger feeds potent acceleration right off idle. The engine is force-fed two liters of cooled, compressed...

Craig Warner carves up the water on the new Jet Ski Ultra 310R. Professional rider on a closed course

OF DOMINANCE It should come as no surprise that the Kawasaki Jet Ski® watercraft has a decades-long history of racing dominance since its introduction in 1973. Whether it be closed-circuit racing on the lake, or off-shore endurance championships, Jet Ski watercraft are consistently emerging victorious—oftentimes sweeping entire top-10s in championship leaderboards. Our stock boats even have a reputation for beating modified competition. But when you’ve got a 310 supercharged engine, and historically dominant riders like 10x champion Craig Warner, no one else really stands a chance.

RACE-INSPIRED TECHNOLOGY. CLASS-LEADING POWER. The Kawasaki Jet Ski Ultra 310R watercraft is turning heads and championship lap times around the lake with a 310-Series supercharged engine and a Deep-V hull that makes it particularly adept at handling choppy water. A sporty riding position and a highly-adjustable post-style racing handlebar prime your 310R for sport riding, while the slim 88mm steering nozzle allows for light, efficient steering—even under full thrust. The Jet Ski Ultra 310R is the epitome of sporty performance and on-water exhilaration. SPORT SEAT This seat is designed...

RACE-INSPIRED HARDWARE ADJUSTABLE HANDLEBAR Similar to the handlebar found on a Kawasaki KX™450F motorcycle, the solid-mounted racing handlebar on the Jet Ski® Ultra® 310R watercraft offers plenty of adjustment to fine-tune your ride.

LXURY SEAT The LXury seat is the most comfortable three-person seat in the industry, and the class-exclusive seat cover material keeps seat temperatures significantly cooler than prior versions. On hot days, this is a huge plus when your 310LX has been sitting outside in the sun. ELECTRONIC CRUISE CONTROL If you’re riding long distance, the electronic cruise control is a massive convenience that is easily activated by pressing a button on the right handlebar switch. Use the UP and DOWN buttons to adjust cruising speed and release the throttle lever to disengage the system easily. Pushing...

FUN THAT’S EFFICIENT FUEL ECONOMY ASSIST MODE Out for a relaxing cruise on the water? The Fuel Economy Assist Mode can significantly extend your ride time. The system can be activated by the push of a button on the top of the left handlebar switch assembly and it switches the ECU to a fuel map that focuses on fuel economy over top power.
