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,
1,498cc 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 60mm 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 82mm 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.
The STX-15F features Kawasaki’s innovative
electronic Smart Learning Operation (SLO). Accessible directly
on the instrument panel, SLO can be programmed to place
a limit on maximum engine speed so novice riders can experience
riding at a reduced speed as they master proper riding
techniques.
Also fitted to every STX-15F is the Kawasaki
Smart Steering® (KSS®).
KSS features an on-board microprocessor that is electronically
linked to a steering sensor. When the handlebar is fully
turned in either direction and the engine rpm drops from
a designated rpm—as when the throttle is released at
speed—the microprocessor activates the system, which
raises engine rpm to provide enough thrust to initiate the
desired turn.
Aggressive turning and high-speed stability
are key performance attributes of the STX-15F. Its specifically
designed injection-molded sponsons have a special “lip” for
increased cornering grip and high-speed stability. Also
incorporated into the hull design is a molded-in Kawasaki
Splash Deflector (KSD) to help minimize spray on the rider.
While the muscular and aggressive looking STX-15F is lighter
and more compact than the competition, Kawasaki engineers
endowed the JET SKI with a roomy riding position that makes
aggressive performance riding easier and suits a wider range
of riders.
Adding to the fresh, high-quality styling of the STX-15F,
the hatch cover is styled from sleek ABS plastic and uses
a hydraulic damper to hold it open, allowing easy access
until the rider closes it. Also made of ABS plastic, the
mirrors echo the sleek lines and are mounted directly to
the deck.
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
reboarding 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 space, an easily accessible
glove box and additional room for gear located under the
seat.
Other features include a LCD instrument panel with fuel
level, speed, engine rpm, trip distance and time information
available. Fuel capacity is a generous 16.4 gallons, for
extended rides. Warning lamps alert the rider to a low fuel
level or high engine temperature, and a magnetic keyed ignition
switch helps deter unauthorized operation.
