2012 Kawasaki Jet Ski STX-15F

The warm summer weather always sends people rushing to the waters. And what better way to soak up the sun and sand than riding the waves on board the Kawasaki STX-15F .

The design of the STX-15F lends itself to a muscular and aggressive looking watercraft, complete with a spacious riding position that makes aggressive performance riding easier while suiting a wider range of riders. A molded-in Kawasaki Splash Deflector (KSD) is incorporated into the hull design to help minimize spray on the rider while an automatically retracting boarding step located on the rear of the hull simplifies boarding in deep water. 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 under the seat.

The STX’s Ninja-derived 1,498cc engine delivers plenty of low- and mid-range torque while also producing 160 horsepower, making it the most powerful watercraft in its class. Despite that, the STX-15F boasts of a Three-Star Ultra-Low Emissions rating from the California Air Resources Board and meets the Environmental Protection Agency’s strictest standards, which means that you can enjoy its spoils without having to worry about destroying Mother Nature.

Aiding the engine to allow the STX-15F to perform the way it does are dual overhead cams, four valves per cylinder, fuel injection, and an electronic engine control (ECU), all of which combine to provide maximum performance and reliability.

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 propelling performance.

Engine

Kawasaki Jet Ski STX-15F
  • Four-stroke engine provides incredibly strong low
  • and mid-range torque
  • Produces 160 horsepower , the most powerful engine in its price range
  • 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 cam 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 degrees
  • Waterproofed ECU and ignition coils protect 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

Quotes

Personal watercraft----"That power makes the 15F an interesting candidate, especially when weighted against more feature-rich machines like the 130hp Sea-Doo GTI series or Yamaha’s 110hp VX models. Is it enough to sway your opinion toward a more basic, possibly even dated-looking craft? It is if you like speed. With a 1,498cc, dual-overhead cam engine, the 15F hits 30 mph in about two seconds, and moves smoothly to a top speed of about 62 mph. That’s a big advantage over its competition, and one that you will certainly appreciate as your skill levels grow with experience. That power is also geared low enough to pull skiers and wakeboarders with a little more ease."
