Safety information

in certain kinds of accidents and that it
could injure you in others.
A helmet is designed to provide some head
protection. Although helmets cannot pro-
tect against all foreseeable impacts, a hel-
met might reduce your injuries in a collision
with a boat or other obstacle.
A helmet may have potential safety haz-
ards, as well. Falling into the water could
risk the chance of the helmet catching wa-
ter, commonly known as “bucketing”, and
the resulting strain on your neck could
cause choking, severe and permanent
neck injuries, or death. A helmet could also
increase the risk of an accident if it reduces
your vision or hearing, or if it distracts you
or increases your fatigue.
How should you decide if a helmet’s poten-
tial safety benefits outweigh its potential
risks for you? Consider your particular rid-
ing conditions. Consider factors such as
your riding environment and your riding
style and ability. Also consider the likeli-
hood of traffic congestion, and the water
surface conditions.
If you decide to wear a helmet based upon
your riding circumstances, choose one
carefully. Look for a helmet designed for
personal watercraft use, if possible. If you
will be engaging in closed-course competi-
tion, follow the helmet requirements of the
sanctioning organization.
Never operate the watercraft after consum-
ing alcohol or taking other drugs.
For reasons of safety and proper care of
the watercraft, always perform the pre-op-
eration checks listed on page 33 before op-
erating the watercraft.
The operator should always keep both feet
or knees on the riding tray when the water-
craft is in motion. Lifting your feet increases the chances of losing your balance or hit-
ting objects outside the watercraft with
your feet.
Always consult your doctor on whether it is
safe for you to operate this watercraft if you
are pregnant or in poor health.
Do not attempt to modify this watercraft.
Modifications to your watercraft may re-
duce safety and reliability, and render the
watercraft unsafe or illegal for use.
Attach the engine shut-off cord (lanyard) to
y o u r l ef t w r is t an d k ee p i t fr e e f r o m t h e h an -
dlebars so that the engine stops if you, the
operator, fall off. After riding, remove the
engine shut-off cord (lanyard) from the wa-
tercraft to avoid accidental starting or un-
authorized use by children or others.
Scan carefully for swimmers, and stay
away from swimming areas. Swimmers are
hard to see and you could accidentally hit
someone in the water.

EJU31124Fuel cock knob
The fuel supply method can be switched by
operating the fuel cock knob.
Select the fuel cock knob position from the
following three positions according to the cir-
cumstances of use.
OFF:
With the fuel cock knob in this position, fuel
does not flow to the carburetors. 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:
With the fuel cock knob in this position, the
fuel reserve is made available. Turn the fuel
cock knob to this position if you run out offuel while operating the watercraft. When this
occurs, refuel as soon as possible and be
sure to turn the fuel cock knob back to “ON”.
EJU31203Choke knob “ ”
The choke knob can be operated to supply a
richer air-fuel mixture that is required to start
a cold engine.
To use the choke:
Pull the choke knob out.
Push the choke knob in to stop using the
choke after the engine starts.
EJU31224Cooling water pilot outlet

proper operation of the cooling system, make
sure that water is being discharged from the
cooling water pilot outlet. If water is not being
discharged from the outlet, stop the engine
and check the jet intake for clogging. (See
page 66 for information on the jet intake.)
TIP:
It will take about 20 seconds for the water
to reach the outlet after the engine is start-
ed.
Water discharge may not be constant
when the engine is running at idling speed.
If this occurs, apply a little throttle to make
sure that water discharges properly.
EJU40323Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water
that has entered the fuel tank breather hose if
the watercraft was capsized.If water has collected in the water separator,
drain it by loosening the drain screw.
To drain water from the water separator:
(1) Place a drain pan or dry cloth under the
water separator.
(2) Gradually loosen the drain screw to drain the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the
watercraft, be sure to wipe it up with a
dry cloth.
(3) Securely tighten the drain screw until it stops.
EJU31665Engine overheat warning system
If the engine temperature rises significantly,
the engine overheat warning system will acti-
vate and the engine speed will be limited to
about 3400 r/min to help prevent damage.

wake, but the watercraft is moving through
the water rather than skimming on top of it.)
At very slow speeds, it may be necessary to
support your upper-body weight with your el-
bows resting on the gunwales, trailing your
legs in the water.
Standing
After you are comfortable handling the water-
craft from a kneeling position, try standing as
the watercraft gains speed. The watercraft
will become easier to balance as the speed
increases, because jet thrust provides stabil-
ity as well as directional control. When you
are moving slowly, or preparing to stop, you
will probably need to return to the kneeling
position to maintain your balance.
EJU32822Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles around you.If the watercraft is launched from a trailer,
someone should make sure that waves do
not push the watercraft into the trailer.
After the watercraft is in the water, turn it
around so that the bow faces the direction
you wish to go.
EJU32836Starting the engine on water
WARNING
EWJ01521
Do not apply throttle when others are at
the rear of the watercraft. Turn the engine
off or keep it at idle. Water and debris ex-
iting the jet thrust nozzle can cause severe
injury.
To start the engine:
(1) Move the watercraft to an area that is
free from weeds and debris, and has a
water depth of at least 60 cm (2 ft) from
the bottom of the watercraft. NOTICE:
Never run the engine in water that is
less than 60 cm (2 ft) deep from the
bottom of the watercraft, otherwise
pebbles or sand could be sucked into
the jet intake, causing impeller dam-
age and engine overheating.
