Introduction
Superb performance at an entry
level price
Based on the popular Kawasaki Jet Ski® STX®-15F, the
new Jet Ski STX watercraft offers the advantages of Kawasaki's
JET SKI® and Ninja® performance know-how in an affordable
vehicle that's destined to please operators who keep an eye on
the bottom line. That means it'll deliver all the waterborne
excitement expected from a JET SKI watercraft and do so with
minimum impact to operating costs.
Designed to offer introductory model cost savings without sacrificing
power and handling, the new STX uses the same responsive engine
and lightweight hull as the STX-15F, but only retains the necessities.
It's a cost-efficient purpose-built runabout that can easily
out-perform its rivals.
Being a Kawasaki, the STX's high-performance matches its high
build quality and proud environmentally friendly four-stroke
heritage. The clean running STX meets strict 2008 CARB emissions
standards, is three-star certified for ultra-low emissions and
continues to shine with features like EVAPO compliant fuel and
filler hose material.
A healthy part of the STX's effortless control and lasting good
times come from the smooth, broad spread of power delivered by
its clean-running, long-stroke, 1,498cc engine. Dual overhead
cams, four valves per cylinder, fuel injection and electronic
engine control (ECU) to harmonize the fuel and ignition
systems provide maximum performance and reliability.
A sophisticated ECU-controlled, four-injector FI system combined
with a large 60mm throttle body delivers quick response. The
STX's four-stroke engine is rubber-mounted and features a large-capacity
airbox and a water-jacketed, performance-tuned exhaust to keep
things quiet.
Thrust is 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's engine rpm matches
the impeller's peak efficiency range ideally, to provide an impressive,
yet rider-friendly experience. This direct drive arrangement
eliminates any need for a complex gear reduction unit, offers
improved durability and increased fuel economy with less vibration
and noise
The STX features Kawasaki's innovative electronic Smart Learning
Operation (SLO) mode. Accessible directly on the instrument panel,
SLO mode can be selected to place a limit on maximum engine speed
so novice riders can be offered reduced power levels and speed,
while they master proper riding techniques.
Aggressive turning and high-speed stability are key performance
attributes of the STX. Its specifically designed injection-molded
sponsons feature a special lip for increased cornering grip and
high-speed stability. The STX also gets electronic turning assistance
via the Kawasaki Smart Steering® (KSS®) system. KSS features
an on-board microprocessor that is electronically linked to a
steering sensor. When the handlebar is fully turned and the engine
rpm is below a designated point - like when the throttle is released
at speed - the microprocessor activates the system, which raises
engine rpm to provide additional thrust to help initiate a turn.
Additionally a molded-in Kawasaki Splash Deflector (KSD) is incorporated
into the hull design to help minimize spray on the rider. The
muscular and aggressive looking STX may be lighter and more compact
than the competition, but it's well endowed with a roomy riding
position that makes aggressive performance riding easier and
suits a wider range of rider sizes.
The spacious rear deck of the STX makes it easy to slip into
water skis or a wakeboard. There is no shortage of space on the
STX watercraft. The rear deck can accommodate most items needed
for a day on the water, along with a water-resistant storage
space, an easily accessible glove box and additional room for
storing gear under the seat. Like the rest of the STX's high-quality
styling, the hatch cover is sleek ABS plastic and uses a hands-free
hydraulic damper to hold it open, allowing unobstructed access
until the rider chooses to close it.
A generous 16.4 gallon fuel capacity allows plenty of riding
time between fill-ups. Simplified from the STX-15F, the STX's
cockpit still has plenty of rider-friendly features, including
an LCD instrument panel with fuel level, speed, engine rpm, trip
distance and time readouts, plus warning lamps to alert the rider
of a low fuel level or high engine temperature, along with a
magnetic keyed ignition switch that helps deter unauthorized
operation.

mass in the valve train
- 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
- Three-blade oval-edge stainless steel impeller pitch provides
maximum efficiency and incredible durability

accordingly for improved appearance
Safety and Reliability
- 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
- Shielded jet propulsion system offers greater protection from
damage
Steering System
- Kawasaki Smart Steering® (KSS®) monitors steering input
and engine speed and, when certain conditions are met, raises
rpm to help initiate a turn
Hull
- Hull size is optimized for a sporty, nimble ride
- Injection-molded sponsons deliver ultra-responsive turning,
while enhancing stability
- Kawasaki Splash Deflector (KSD) helps keep spray off the operator
and passenger
- Large capacity fuel tank reduces number of refueling breaks
during a day on the water
Deck
- Stylish hatch cover keeps with muscular look
- Steering handle position makes aggressive "stand-up"
riding easier and provides ample room for a wide range of riders
- Comfortable and low maintenance, one-piece seat
- 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
