Introduction

The STX®-15F combines over 30 years of JET SKI® knowledge and renowned Ninja® motorcycle heritage to deliver the pure waterborne excitement that knowledgeable enthusiasts demand from Kawasaki JET SKI watercraft. A healthy part of its effortless control and lasting performance comes from the broad and smooth spread of power delivered by its clean-running, four-stroke, 1,498cc engine.
 
Details & Features

1,498cc Engine
• Four-stroke engine provides incredibly strong low
• and mid-range torque
• Dual overhead cams (DOHC) are light and compact for less valve train inertial mass
• Large valves provide better intake and exhaust flow to improve torque and power
• Intake and exhaust valve lift as well as timing are optimized to reduce exhaust emissions
• Large capacity airbox cuts down engine noise and provides good air intake flow
• Intake tract designed for maximum performance
• Digital fuel injection provides great throttle response, smooth engine performance, quick acceleration, easy starting and excellent fuel economy
• Tip-over protection shuts engine off if craft tilts more than 61°
• Waterproofed ECU and ignition coils protects the ignition system from electrical shorts
• Unique semi-dry sump oil system lowers the crankshaft in the engine, eliminates the need for scavenging pumps, and keeps the oil from flooding the crankcase if the craft is capsized
• Kawasaki’s patented oil separator provides fail-safe venting for the crankcase and prevents oil from flowing into the intake tract if the craft is capsized
• Has earned a Three-Star UltraLow Emissions rating, meets the Environmental Protection Agency’s strictest standards, as well as the California Air Resources Board standards
Steering System
• Kawasaki Smart Steering® (KSS®) monitors steering input and engine speed and, when certain conditions are met, raises rpm to give enough thrust to maneuver
• Reverse bucket is designed for more precise direction control when backing and is made of injection molded material to prevent corrosion
• Reverse increases maneuverability in tight places
Composite Hull
• Hull size is optimized for a sporty, nimble ride
• Injection-molded sponsons deliver ultra-responsive turning, while enhancing stability
• Three-blade oval-edge stainless steel impeller pitch provides maximum efficiency and incredible durability
• Shielded jet propulsion system offers greater protection from damage
• Kawasaki Splash Deflector (KSD) helps keep spray off the operator and passenger
• Boarding step retracts automatically and eases boarding in deep water
• Large capacity fuel tank allows more time on the water
Deck
• Stylish hatch cover keeps with muscular look
• Handle position makes aggressive “stand-up” riding easier and provides ample room for a wide range of riders
• Spacious, close-to-the-water open rear deck provides plenty of spacious area for putting on skis or a wakeboard and easy deep water boarding
