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.
