The STX-15F is the result of combining a high-revving, large-displacement 4-stroke engine and a compact, sporty-handling hull. Boasting a maximum output of more than 160 ps, the 4-cylinder, DOHC engine gives the STX-15F awesome performance.

Ninja Engine Technology
The 4-stroke, 4-cylinder engine is developed using Kawasaki Ninja motorcycle technology. DOHC, 16-valve, fuel-injected, in-line Four engine displaces 1,498 cc

Sophisticated ECU-controlled fuel injection system
Electronic fuel injection system delivers hard-hitting throttle response. Throttle body diameter of 60 mm ensures quick response and high power output at all rpm.

Water Jacketed Semi-Dry Exhaust System
Double-walled exhaust manifold helps reduce noise. Water surrounding the exhaust system lowers engine compartment temperatures for more power. The semi-dry exhaust system keeps cooling water out of the exhaust before the waterbox to prevent water from entering the engine if the boat should capsize. Dual waterboxes lower noise. Reduced emissions make this one of the cleanest watercraft around.

Kawasaki Smart Steering KSS
A steering sensor is linked to the ECU to aid in boat handling when the throttle is quickly released at high speed. This helps avoid possible collision especially for less experienced riders.

Kawasaki Smart Learing Operation
The smart learing operation (SLO) mode is designed to help new riders learn to operate a Kawasaki Jet Ski watercraft at a more relaxed pace. In SLO mode, engine RPM is electronically restricted by the ECU to restrict engine power and speed.

Plenty of Space
The spacious rear deck of the STX-15F makes it easy to get into water skis or on a wakeboard. An automatically retracting boarding step located on the rear of the hull simplifies oarding in deep water. There is no shortage of space to stow items on the STX-15F. The rear deck can accommodate items needed for a day on the water, like a cooler, along with a water-resistant storage compartment, an easily accessible glove box and additional room for gear located under the seat.
