Performance bargain watercraft has the heart of a Nnnja! Many personal watercraft boast tremendous performance and state-of-the-art features, while other models offer a good bang for the buck if you’re willing to compromise on some aspects. The Kawasaki JET SKI® STX®-15F, however, is one watercraft that doesn’t compromise performance for value. With a powerful four-stroke engine, a sporty composite hull and plenty of rider-friendly features, the STX-15F will be the bargain of the summer for enthusiasts seeking fun on the water.

Powertrain

The STX-15F proudly carries the heart of a Ninja® motorcycle.Derived from Kawasaki’s class-leading Ninja ZX™-14R sportbike, its 1,498cc engine delivers plenty of low- and mid-range torque while generating an impressive 160hp².

The engine blends the best of both worlds by delivering snappy performance with excellent fuel economy and low emissions. In fact, the STX-15F has earned a Three-Star Ultra-Low Emissions rating from the California Air Resources Board, and meets the Environmental Protection Agency’s strictest standards.

Dual overhead camshafts, four-valves-per-cylinder and Digital Fuel Injection provide maximum performance and reliability. A four-injector fuel injection system combined with a large 60mm throttle body delivers quick responses to rider inputs. The STX-15F’s four-stroke engine is rubber mounted to isolate vibration, and features a performance-tuned exhaust as well as a large-capacity airbox.

Propulsion System

Propulsion duties are handled by a direct-drive, axial-flow jet pump driving an oval-edge, stainless steel, three-blade 148mm impeller for powerful acceleration. Tuned to produce its peak power at a relatively low RPM, the STX-15F engine matches the impeller’s peak efficiency to provide rider-friendly performance. This direct drive arrangement eliminates the need for a complex gear reduction unit and offers improved durability and increased fuel economy with less vibration and noise.

The STX-15F personal watercraft (PWC) also features Kawasaki’s innovative electronic Smart Learning Operation (SLO). Accessible from the instrument panel, SLO can be programmed to limit maximum engine speed so novices can experience riding at a reduced speed as they master proper techniques.

Hull Design

Aggressive turns and high-speed stability are key performance attributes of the STX-15F. Its specially designed injection-molded sponsons have a molded “lip” for increased cornering grip and high-speed tracking.

The STX-15F PWC also gets turning assistance tanks to its Kawasaki Smart Steering® (KSS®) system. KSS employs an on-board microprocessor linked to a steering sensor. When the handlebar is fully turned in either direction, and engine RPM drops below a designated setting – such as when the throttle is released at speed – the microprocessor activates the system to raise RPM and provide thrust for maneuvering. Additionally, a molded Kawasaki Splash Deflector (KSD) is incorporated into the hull to help minimize spray on the occupants.

The muscular and aggressive-looking STX-15F, which is available in an Ebony and Lime Green color, might be lighter and more compact than some of the competition, but its spacious riding position makes its sporty performance easier to access for a rider range of riders.

Ergonomics and Storage

The spacious rear deck of the STX-15F makes it easy to fit water skis or climb onto a wakeboard. An automatically retracting boarding step is located on the rear of the hull to simplify boarding when in deep water.

There is no shortage of space to stow items on the STX-15F. The rear deck can accommodate gear needed for a day on the water, such as a cooler. There is also a water-resistant storage compartment, an easily accessible glovebox and dditional storage space under the seat.

The hatch cover is made from resilient ABS plastic and uses a hydraulic damper to hold it open, allowing easy access until the rider closes it. The mirrors are also ABS plastic and echo the sleek lines of the Jet Ski watercraft, being mounted directly to the top deck.

A generous 16.4-gallon fuel capacity allows extended rides, during which there is plenty of time to enjoy the cockpit features. These include an LCD instrument panel with fuel level, speed, engine RPM, trip distance and a clock available, with warning lamps to alert the rider of a low fuel level or high engine temperature, along with a magnetic-keyed ignition switch that helps deter unauthorized operation.

160hp 1,498cc Engine
- * The four-stroke engine provides strong low- and mid-range torque
- * The most powerful engine in its price range
- * Dual overhead camshafts (DOHC) are light and compact for less valvetrain inertia
- * Large valves provide better intake and exhaust flow to improve power and torque
- * Large capacity airbox cuts down engine noise and provides good intake flow
