Extended Cruising Range

Offering more fuel capacity than any machine in its class, the Ultra 300X’s 78-litre fuel tank holds 14 litres more than the JET SKI STX-15F, making long distance cruising even more accessible and inviting.

Exhaust

The Ultra 300X features a 4-into-2-into-1 powerboat-style exhaust system, which routes the exhaust pipe upwards. This allows the smoothest flow for exhaust gases, maximising exhaust efficiency.

Fuel Injected

High-flow fuel injectors with 4 orifices are fitted to complement the increased power output and to improve combustion efficiency. A single throttle body is used with a bore diameter of 60 mm.

New Impeller

To suit the new 160 mm jet pump, the Ultra 300X gets a new impeller redesigned to efficiently convert all the extra power into forward thrust.

New Race Bred Hull Design

Designed using feedback from Kawasaki's IJSBA Championship winning machines, the new hull now features two separate flush ports for the engine and intercooler and offers the industry's best stability responsive handling in calm and rough water. Deep 22.5 degree V-angle at the bottom of the hull provides better "grip" for racing like performance.

Jet Pump

To effectively convert the 300 PS output into thrust, the Ultra 300X utilises a new, larger 160mm jet pump, designed using eight guide vanes. The pump delivers superior “traction” in rough water conditions and significantly contributes to the Ultra 300X’s mind-boggling acceleration.

Intercooler

Pressurising the intake air heats it to extremely high temperatures which would rob power, but the liquid-cooled intercooler reduces intake air to ambient temperature, or even less, for higher combustion efficiency and more power.

Adjustable Handlebars

The handlebars are 5-way adjustable and suit a wide range of riders and riding styles and allows comfortable stand-up or seated riding positions. The redesigned left side reverse control is even easier to use.

Electronic Trim Control System

Electronic Trim Control System allows the rider to control the angle of the jet pump nozzle to suit water surface conditions and riding style.

Electronic Throttle Valve

The Electronic Throttle Valve operated by the thumb throttle on the handlebar makes throttle action very light for reduced rider fatigue and the more precise throttle control results in better performance, smoother running and increased fuel economy.

Large Capacity Storage

The huge 200 litre front storage compartment comes with removable tray. There's also a centre console storage area with a detachable drink holder with space for two water bottles

Kawasaki Smart Steering

Designed to assist inexperienced riders, the Kawasaki Smart Steering system is electronically linked to an on-board microprocessor and automatically adjusts engine speed and thrust while cornering to ensure a smooth, controlled turn.

Multiple Riding Modes

The ECU controlled ETV allows multiple riding mode options to be activated with the touch of a button. 8 kph mode conveniently regulates rpm to maintain constant speed in no-wake zones and cruise control fixes speed at a specified level for convenient long distance touring.

Supercharged

The Ultra 300X’s liquid-cooled 1,498 cm3, In-line 4-cylinder engine got new pistons, cam shaft and conrods in 2011. The TVS Eaton supercharger uses twin four-lobe rotors to produce a continuos delivery of air, giving the Ultra 300X an output of 300 PS reclaiming the title as the most powerful production PWC in the world.

All New Instrument Panel

The LCD screen is easy to read and also displays water and air temperature in addition to the speedometer, tachometer, hour meter, clock, trip distance, trip time and fuel level. It is also positioned higher on the hull with a revised visor for improved visibility.

Beginner Friendly

The Ultra 300X features Kawasaki’s innovative electronic Smart Learning Operation (SLO) system which can be programmed to speed-limit the engine to assist novice riders in mastering their riding technique without worrying about excessive speeds.
