| Few experiences are as pleasurable as gliding across
the open water on a personal watercraft, with a cool
breeze blowing and a sandy white beach beckoning in
the distance. The experience is even better when it’s
done on a JET SKI® STX®-12F watercraft, a model
that combines more than 20 years of Kawasaki’s
high-performance NINJA® motorcycle technology with
quiet operation and the best emissions rating in the
industry.
The engine of the STX-12F was adapted from Kawasaki’s
powerful NINJA® ZX-12R motorcycle. The 1,199cc water-cooled
engine with dual overhead camshafts pumps out plenty
of power for optimum performance and boasts low emissions
while purring quietly on the water.
The environmentally friendly STX-12F meets the strictest
existing emission standards for both the Environmental
Protection Agency and the California Air Resources Board
(CARB). In fact, the STX-12F received CARB’s ultra-low
“three-star” rating in 2003, a full five
years prior to the mandated time limit.
The STX-12F features dual overhead cams, four valves
per cylinder, fuel injection and an electronic engine
control unit (ECU) that harmonizes the fuel system and
the ignition system to provide maximum performance
and reliability.
The fuel injection system utilizes a single 54mm throttle
body and individual injectors at each chrome composite
plated aluminum cylinder to provide fuel for this high-performance
NINJA-based engine, resulting in smooth power delivery
and instant starting in both hot and cold weather.
The engine’s highly tuned exhaust system is water-jacketed
to help reduce underhood temperatures and keep the STX-12F
running as quietly as possible. The
STX-12F also features dual water mufflers for very
low exhaust noise. The large capacity airbox is specially
designed to reduce noise levels and the engine is rubber-mounted
in the hull to reduce vibration.
The STX-12F features an open-loop cooling system that
utilizes an intake filter and draws cooling water from
the jet pump, providing the STX-12F with consistent
operating temperatures for maximum performance.
The JET SKI STX-12F utilizes a direct drive axial-flow
pump that is connected to an oval-edge, stainless steel,
three-blade impeller. The STX-12F direct drive has no
gear reduction unit, allowing the STX-12F’s engine
to turn a lower rpm for less stress and wear and tear,
less vibration, less noise and better fuel consumption.
A reverse function allows for easy maneuverability in
tight quarters.
The JET SKI STX-12F also features Kawasaki Smart Steering®
(KSS®). The Kawasaki Smart Steering system features
a steering sensor that is electronically linked to an
on-board microprocessor. If the handlebar is fully turned
in either direction and the engine rpm drops from a
designated rpm, such as when the throttle is released
at speed, the microprocessor activates the KSS, which
raises engine rpm to provide enough thrust to initiate
the desired turn.
Smart Steering can assist riders in learning to negotiate
turns and to maneuver, making turning easier and smoother.
Experienced riders may not feel the system functioning
since they realize throttle application is required
during turning.
The STX-12F’s deep-V hull is made of fiberglass
and gel-coated for a lustrous, scratch-resistant finish
and features the molded-in Kawasaki Splash Deflector
(KSD) to help minimize spray on the operator. The one-piece
hull construction increases durability while decreasing
weight, and high-performance sponsons help get the hull
up on plane and provide “grip” while the
hull design facilitates precise cornering, increased
stability at high speed and a smoother ride in rough
water.
The STX-12F boasts a sporty design with its stylish
deck and angular seat, offering a muscular look befitting
a high-performance watercraft. The handlebars are located
in a cab-forward position to provide plenty of room
for the rider, plus abundant floor space provides room
for the rider’s feet. There are even footrests
to help stabilize a rear-facing spotter when pulling
a skier, wakeboarder or tuber.
The open rear deck features abundant space easily used
for getting into skis or as a diving platform. Reboarding
in deep water is simplified with the automatically retracting
boarding step located at the rear of the hull.
The rear deck can also accommodate a cooler or other
items needed for a day on the water. The STX-12F features
water-resistant storage space, an easily accessible
glove box and front storage compartment. A hydraulic
damper holds the front storage hood open, allowing easy
access until the operator closes it. Another large storage
area is located under the seat.
The JET SKI STX-12F features a 16.4-gallon fuel tank
for more riding time between fill-ups and an LCD instrument
panel allows riders to monitor fuel level, speed, engine
rpm, trip distance and time. Warning lamps alert the
rider to low fuel level or high engine temperature.
In addition, there is a magnetic keyed ignition switch
to help deter theft or unauthorized use.
Features
- Large 1,199cc four-stroke engine provides incredibly
strong low-speed torque and acceleration
- Electronic fuel injection provides improved throttle
response, smooth engine performance, quicker acceleration,
instant starts under most conditions and a dramatic
reduction in fuel consumption
- Dual overhead cams (DOHC) are light and compact for
less valve train inertial mass, and provide consistent
valve timing at high rpm
- Four-valve cylinder head with large valves provide
better intake and exhaust flow to improve torque and
power
- Tip-over protection shuts engine off if craft tilts
more than 61°
- Waterproof 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 if the craft is capsized the oil stays in the sump
instead of flooding the crankcase
