Power King of Fun

Kawasaki introduced the JET SKI name to the world over 40 years ago and now, after decades of technological development, Kawasaki used all of our experience and know-how to build the ultimate high-performance, large capacity watercraft: the all-conquering STX-15F 4-stroke JET SKI.

The Kawasaki JET SKI STX-15F is one watercraft that does not compromise performance for value. With a powerful four-stroke engine, a sporty-handling composite hull and plenty of rider-friendly features, the STX-15F is great value for enthusiasts seeking fun on the water.

Casual cruising with a couple of passengers, towing a water skier across your local dam or screaming along the coastline on your own, the STX-15F will blow your expectations into the sunset.  The perfect Jet Ski for easy use and pure joy of riding a person water craft.

Refined Fun and Performance

The JET SKI ULTRA LX comes equipped with the high-performance hull of the ULTRA 310 Series.

Loaded with technology from Kawasaki’s championship winning machines, the race-developed hull handles with precision and stability, with a high level of seaworthiness.

In addition to contributing to the Ultra LX’s improved handling in both rough and calm water, the idealised strength balance helps realise a much lighter package. A revised steering nozzle also contributes to the much lighter handling.

A generous three-seater that encourages family fun.

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.

Powerful 4-Stroke Engine

The STX-15F’s high-performance, 1,498cc, 4 cylinder, DOHC, fuel injected, 4-stroke engine was adapted from technology developed through Kawasaki’s leading edge range of Ninja sports motorcycles.

LCD Digital Dashboard

Multi-function digital instrumentation includes a digital speedometer, tachometer, fuel gauge, hour meter, trip meter, clock and warning lights for high temperature, low oil pressure, immobiliser, low battery voltage and EFI system.

Low Emission Output

Thanks to clever engine design and precise tuning, the STX-15F boasts extremely low emission outputs, meeting the strictest existing emission standards issued by the Environmental Protection Agency (EPA) compatible with future Australian emission regulations.

Easy Reversing

Greatly assisting low-speed manoeuvring is a reverse ‘bucket’ fitted to the steering nozzle. Shaped to deliver optimal thrust and directional control when reversing, the bucket is made from injection moulded plastic, which virtually eliminates corrosion.

Superior Hull Design

The STX-15F’s deep-V hull is made of fibreglass and gel-coated for a lustrous, scratch-resistant finish and features the moulded-in Kawasaki Splash Deflector (KSD) to help minimize spray on the operator. High-performance sponsons help get the hull up on plane and provide “grip” while the hull design facilitates precise cornering, increased stability at high speed and a smoother ride in rough water.

Spacious Rear Deck

The open rear deck has plenty of space well suited for getting into water skis or for use as a diving platform, and its close-to-the-water height and automatically retracting boarding step make boarding in deep water a breeze.

Kawasaki SLO-Mode

The STX-15F features Kawasaki’s electronic Smart Learning Operation (SLO)-Mode function allows new riders to become familiar with the handling and response of this JET SKI watercraft at a relaxed pace before operating the STX-15F at full power.  Two separate keys (Yellow for SLO-mode, Green key for full-power operation) prevent operating mistakes.
