Enjoy your watercraft
responsibly
You share the areas you enjoy when riding
your watercraft with others and with nature.
So your enjoyment includes a responsibility to
treat these other people, and the lands, wa-
ters, and wildlife with respect and courtesy.
Whenever and wherever you ride, think of
yourself as the guest of those around you. Re-
member, for example, that the sound of your
watercraft may be music to you, but it could be
just noise to others. And the exciting splash of
your wake can make waves others won’t en-
joy.
Avoid riding close to shoreline homes and wa-
terfowl nesting areas or other wildlife areas,
and keep a respectful distance from fisher-
men, other boats, swimmers, and populated
beaches. When travel in areas like these is
unavoidable, ride slowly and obey all laws.
Proper maintenance is necessary to ensure
that the exhaust emission and sound levels of
your watercraft will continue to be within regu-
lated limits. You have the responsibility to
make sure that the recommended mainte-
nance in this owner’s/operator’s manual is
carried out.
Remember, pollution can be harmful to the
environment. Do not refuel or add oil where a
spill could cause damage to nature. Remove
your watercraft from the water and move it
away from the shoreline before refueling. Dis-
pose of water and any fuel and oil residue in
the engine compartment according to local
regulations. And keep your surroundings
pleasant for the people and wildlife that share
the waterways: don’t litter.
When you ride responsibly, with respect and
courtesy for others, you help ensure that ourwaterways stay open for the enjoyment of a
variety of recreational opportunities.

The fuel cock knob positions are explained as
follows and are shown in the illustration.
OFF:
With the fuel cock knob in this position, fuel
does not flow. Always turn the fuel cock knob
to this position when the engine is not running.
ON:
With the fuel cock knob in this position, fuel
flows to the carburetors. Turn the fuel cock
knob to this position when starting the engine
and operating the watercraft.
RES:
This indicates reserve. With the fuel cock
knob in this position, the fuel reserve is made
available. Turn the fuel cock knob to this posi-
tion if you run out of fuel while operating the
watercraft. When this occurs, refuel as soon
as possible and be sure to turn the fuel cock
knob back to “ON”.EJU31150Engine stop switch

(lanyard) to your left wrist, and then insert the
clip on the other end under the engine shut-off
switch (black button). The engine will stop au-
tomatically when the clip is removed from the
switch, such as if the operator falls off the wa-
tercraft. Remove the engine shut-off cord
(lanyard) from the watercraft when the engine

When the engine is running, cooling water is
circulated in the engine, and then it is dis-
charged from the pilot outlet.
To check for proper operation of the cooling
system, check that water is being discharged
from the pilot outlet. If water is not being dis-
charged from the outlet, cooling water may
not be circulating in the engine. When this oc-
curs, stop the engine and check for the cause.
(See pages 22 and 63 for more information.)
TIP:

If the cooling water passages are dry, it will
take about 20 seconds for the water to
reach the outlet after the engine is started.

Water discharge may not be constant at
idle, therefore, open the throttle a little to
check that water discharges properly.
EJU35930Steering system
Your watercraft can be steered by turning the
handlebars in the direction you wish to travel.
When the handlebars are turned, the angle of
the jet thrust nozzle is changed, and the direc-
tion of the watercraft is changed accordingly.
Since the strength of the jet thrust determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn, ex-
cept at trolling speed.
The angle of the jet thrust nozzle can be ad-
justed to suit operator preference. (See page
53 for adjustment procedures.)

EJU31270Steering pole
The steering pole varies in height with the op-
erator’s posture, enabling the operator to as-
sume various riding positions.
When removing the hood for pre-operation
checks, maintenance, etc., lift the steering
pole and use the lock pin to support it. Move
the lock pin into the detent. Make sure that the
lock pin is returned to the stowed position af-
ter installing the hood.
EJU36000Bow rope hole

EJU31661Engine overheat warning system
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the engine
speed will be limited to about 3400 r/min.
If this occurs, immediately reduce the engine
speed, return to shore, and then check for wa-
ter discharge at the cooling water pilot outlet
while the engine is running. If there is no dis-
charge of water, check the intake grate and
