Ultra 310X The Fastest JetSki on the Planet just Got Faster!! Personal watercraft (PWC) innovators for four decades, Kawasaki surprised the entire industry when it debuted the Jet Ski Ultra 300X watercraft. Now a substantially improved Jet Ski, Ultra 310X watercraft, raises the PWC stakes before the competition has even had a chance to place a 300 class bet! With incredible boost from an Eaton Twin Vortices Supercharger, the big Kawasaki Ninja-inspired marine engine pumps out 300 horsepower* through an all new pump for incredible hook-up and acceleration. Not only is the Ultra 310X high powered, but it’s also high-tech. Riders can adjust hull attitude with the electric trim system, there’s an electronic throttle valve with electronic cruise control, fuel saving ECO mode and an all digital instrument panel. * Measured in PS at the crankshaft under controlled conditions. Actual performance may vary. KEY FEATURES UPGRADED Supercharged DOHC inline four-cylinder engine produces a staggering 310 horsepower, it’s the most powerful production PWC in history UPGRADED Impeller features a revised 3-blade design that gives the 310X greater initial acceleration Strong and light, the 310X’s deep-V hull offers superb straight-line tracking and precise cornering performance NEW Instrumentation includes a new fuel consumption function, revised boost meter scale, riding modes, external water and air temperature, clock, time, trip and hour meters, tachometer (in digital or graph displays), speedometer and max speed functions Eaton TVS constant-displacement supercharger and liquid-cooled intercooler provide instant and consistent boost for outstanding performance throughout the rev range Industry-leading, 212L storage capacity lets you bring your gear with you 78L fuel tank is the largest in its class, providing tremendous range for long rides Separate keys for full power operation and Smart Learning Operation 310 HORSEPOWER SUPERCHARGED ENGINE UPGRADED 1,498cc, liquid-cooled inline four-cylinder engine makes 10 additional horsepower through reduced mechanical loss, improved efficiency. The Eaton TVS constant-displacement supercharger and liquid-cooled intercooler provide instant and consistent boost for outstanding performance throughout the rev range. NEW Heat-resistant plastic intake manifold is reshaped for improved low-mid range power NEW Cast pistons feature additional ring land V-grooves for better oil retention Hardened nickel 33.4mm intake and 28.3mm exhaust valves offer superior reliability Two-layer oil cooler offers efficient cooling Large cam chain increases reliability in a supercharged engine application Reinforced crankcase adds to engine’s durability and reliability NEW Fuel pump provides greater fuel flow volume for increased power and better fuel efficiency NEW Thicker water jackets improve cooling performance Check valve system between the cylinder jacket and water muffler that shuts water flow off above 2,000 rpm, to keep the cooling water inside the cylinder jacket for optimum cooling performance NEW Piston cooling oil jets increased from one jet per piston to two jets per piston for increased piston cooling NEW Oil pan features additional baffle plates to prevent oil slosh during tight turns or extreme acceleration/deceleration NEW Crankcase oil return holes are enlarged for quicker oil return to the oil pan *Horsepower measured in PS at the crankshaft under controlled conditions.
