The Kawasaki JET SKI 900 STX® watercraft features the solid performance, sleek hull and top-grade amenities normally reserved for more expensive three-person models.

For example: in addition to its powerful 891cc two-stroke engine, the JET SKI 900 STX also features innovative Kawasaki Smart Steering®® (KSS). KSS features a steering sensor that is electronically linked to an on-board microprocessor. If the handlebar is fully turned in either direction and the engine rpm drops from a designated rpm, such as when the throttle is released at speed, the microprocessor activates the KSS, which raises engine rpm to provide enough thrust to initiate a turn.

The JET SKI 900 STX watercraft has a 16.4-gallon fuel tank for extended cruises and an easy-to-use freshwater flush fitting. The freshwater flush fitting is adaptable to a standard garden hose and allows operators to easily rinse out the motor's cooling lines.

The hull of the 900 STX is made of fiberglass and gel-coated for a deep, lustrous, scratch-resistant finish, and features the molded-in Kawasaki Splash Deflector (KSD) to help minimize water spray on the operator. High-performance sponsons help get the hull up on plane and provide more aggressive “grip.” The hull also features a deep keel and long strakes located close to the center of the deep-V. These design enhancements give the 900 STX better wave cushioning, excellent cornering, increased top speed and greater stability.

The 900 STX watercraft provides a smooth and comfortable ride for up to three people and features an open rear deck with ample space for putting on skis. The stable design makes boarding in deep water easier, while an optional rear boarding step can be easily attached to the 900 STX.

Also featured are more than 23 gallons of storage space and full digital instrumentation, including fuel and oil level gauges, speedometer, tachometer, trip meter, digital clock and time elapsed function. There are adjustable rear-view mirrors, finger throttle control, a handy glove box in front of the seat, a water-resistant canister to help keep the tool kit dry and a magnetic ignition switch provides an extra level of security.
