2008 Kawasaki Jet Ski® STX®-15F

Jet Ski® STX®-15F
Pure waterborne fun, Kawasaki Jet Ski style. With a high-performance engine from the legendary Kawasaki Ninja® motorcycle line as its foundation, the JET SKI® STX® -15F delivers the kind of performance expected from a Kawasaki JET SKI watercraft. A smooth spread of power across the entire rpm range thanks the flat torque curve out of the long-stroke, 1,498 cubic centimeter engine ensures plenty of good times. Dual overhead cams, four-valves per cylinder, fuel injection and electronic engine control—to harmonize the fuel and ignition systems—provide maximum performance and reliability. A four-injector fuel injection system combined with a large 60 millimeter throttle body deliver a quick response. High-performance with high standards; the STX-15F has earned a Three-Star Ultra-Low Emissions rating, meeting the Environmental Protection Agency’s (EPA) strictest standards, as well as the California Air Resources Board (CARB) standards for 2008. Refined as it is clean-running, the STX-15F’s four-stroke engine is rubber-mounted in the hull, the performance-tuned exhaust system is water-jacketed, and it has dual mufflers and a large-capacity airbox. Propulsion duties are handled by a direct drive axial-flow jet pump driving an oval-edge, stainless steel, three-blade impeller and an 82 millimeter jet pump nozzle for powerful acceleration. Tuned to produce its peak power at a relatively low rpm, the STX-15F engine matches the impeller’s peak efficiency rpm ideally to provide a rider-friendly propelling performance. This direct drive arrangement eliminates any need for a complex gear reduction unit and offers improved durability and increased fuel economy with less vibration and noise.
