Kawasaki Jet Ski Ultra 310X

Kawasaki JET SKI personal watercraft have a long history of high performance. While the JET SKI ULTRA 300X and 300LX are already known as powerhouses on the water,
Kawasaki engineers were still not satisfied. By increasing engine efficiency they were able to increase output of the supercharged engine to 310 PS* – the highest in JET SKI’s 40-year history – to ensure the JET SKI brand remains synonymous with personal watercraft supremacy.

DOMINANT PERFORMANCE

1500cc In-line Four engine with TVS Roots supercharger delivers highest output in Jet Ski history: 310 PS

HIGH PERFORMANCE HULL DESIGN

Hull balances strength and light weight to handle 310 PS output – High stability and responsive handling in both calm and rough water

ELECTRIC THROTTLE VALVES

Electronic throttle valves manage high power output efficiently, enable numerous riding modes: Electronic Cruise Control. Fuel Economy Assistance Mode. One-touch 5 mph Mode. Smart Learning Operation (SLO)-Mode

5-WAY ADJUSTABLE HANDLE

The models of the ULTRA 310 Series (except the ULTRA 310R – please see below) feature a 5-way adjustable handle that suits a wide range of riders and riding styles, allowing either standup or sit-down riding.

RIDING POSITION AND ERGONOMICS

Ergonomics on the ULTRA 310 Series models were designed to comfortably accommodate three people, as well as facilitate both stand-up and seated riding

IMMOBILISER

Immobiliser function incorporated into the ignition switch helps prevent theft. Works with both keys (full-power and SLO-mode versions).

QUATTRO KSD

Ridges across the bottom of the bow, Kawasaki Splash Deflectors deflect water splashing forward from under the hull. A fourth splash deflector mounted at the top reduces spray during high-speed turns. Whether turning or blasting straight ahead, at high speeds or low, the Quattro KSD minimises spray, allowing greater rider concentration.

ELECTRIC TRIM-CONTROL SYSTEM

This convenient system allows the angle of the jet pump nozzle to be controlled electrically (step-free adjustment range is +/- 8° from STD), making it easier for riders to adjust the attitude of the hull to suit water surface conditions and riding style.

ALL-DIGITAL INSTRUMENTATION

Instrumentation accommodates the engine’s various riding modes, as well as a new Current Fuel Consumption (measured at 1 second intervals) function. External Water Temperature, Air Temperature, Clock, Time, Trip, Hour Meter, Tachometer (digital display or bar graph), Speedometer, Max Speed functions are available as before. * Instrument panel position and cockpit visor design were selected to ensure high visibility.

KAWASAKI SMART STEERING/SLO-MODE

Smart Learning Operation (SLO)-Mode function allows newer riders to become familiar with the handling and response of this JET SKI watercraft at a more relaxed pace before unleashing the full power of the supercharged engine. Two separate keys (one for SLO-mode, one for full-power operation) make it easy for operators to know which operating mode they are using.
