Post-operation checks
Always perform the following post-opera-
tion checks after operating the watercraft.
1. Remove the watercraft from the water.
2. Wash down the hull, handlebars, and jet
unit with fresh water.
3. Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, then
raise the bow of the watercraft enough to
allow water in the bilge to drain out.
NOTE:
This watercraft is equipped with an auto-
matic bilge-draining system that removes
water from the engine compartment while
you are underway. However, some residual
water will remain.
4. Put the watercraft in a horizontal posi-
tion.
5. Flush the cooling system to prevent it
from clogging with salt, sand, or dirt.
(See page 4-1 for flushing the cooling
system procedures.)
6. Drain residual water from the exhaust
system by alternately squeezing and
releasing the throttle lever for 10 to
15 seconds while the engine is running.
CAUTION:
Do not attempt to run the engine at full
throttle or for more than 15 seconds
while the watercraft is out of the water,
otherwise the engine may overheat or
seize.

Fuel system
Draining the fuel system prevents buildup
of varnishes and other harmful deposits that
result when gasoline sits for a prolonged
period of time.
WARNING@Gasoline is highly flammable and explo-
sive. A fire or explosion can cause
severe injury or death. Shut the engine
off. Refuel in well-ventilated areas away
from flames or sparks. Do not smoke.
Avoid spilling gasoline. Wipe up spilled
gasoline immediately.
@
To drain the fuel system:
1. Place the fuel cock knob in the “OFF”
position.
2. Drain the fuel tank using a siphon.

Battery
When the watercraft is not to be used for
a month or more, remove the battery and
store it in a cool, dark place. Clean the bat-
tery casing using fresh water. Clean the bat-
tery terminals. Apply dielectric grease or
petroleum jelly to the battery terminals and
to all exposed battery leads.
If the battery is to be stored for a longer
period, check the specific gravity of the elec-
trolyte at least once a month and charge the
battery if necessary.
Specific gravity: 1.28 at 20 °C (68 °F)

Emergency procedures
EJU00598
Cleaning the jet intake and
impeller
If weeds or debris get caught in the intake
or impeller, cavitation can occur, causing jet
thrust to decrease even though engine
speed rises. If this condition is allowed to
continue, the engine will overheat and may
seize. If there is any sign that the jet intake
or impeller is clogged with weeds or debris,
beach the watercraft and check the intake
and impeller. Always stop the engine before
beaching the watercraft.
WARNING
Before attempting to remove weeds or
debris from the jet intake or impeller
areas, shut the engine off and remove
the clip from the engine shut-off switch.
Severe injury or death could result from
contact with the rotating parts of the jet
pump.
1. Turn the watercraft on its side as shown.
CAUTION:
●Place a suitable clean cloth or carpet-
ing underneath the watercraft to pro-
tect it from abrasions and scratches.
●Always turn the watercraft over onto
its port (left) side.
●When turning the watercraft on its
side, support the bow so the handle-
bars cannot be bent or damaged.
