Gasoline
WARNING@ GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.

Stop engine before refueling.

Refuel in a well-ventilated area. Do not
stand or sit on the watercraft while
refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level just reaches the
bottom of the filler tube. Do not fill up
the filler tube because fuel expands as
it warms up and could overflow.

Tighten the filler cap securely after
refueling.

If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.

If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.
@
CAUTION:@ Use only fresh gasoline that has been
stored in clean containers.
@
Recommended gasoline:
Regular unleaded gasoline with a
minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)

Engine compartment
Ventilate the engine compartment, before
each use. To ventilate the engine compart-
ment, lift the steering pole and support it
with the stopper pin, then remove the hood.
Put the hood aside for a few minutes to allow
any fuel vapors to escape. Also, check for
loose electrical connections.
WARNING@ Failure to ventilate the engine compart-
ment could result in fire or explosion. Do
not start the engine if there is a fuel leak
or loose electrical connection.

tainer up more than 30 degrees from the
storage position, otherwise the container
or hood could be damaged.
@
To close the fire extinguisher container:
1. Reinstall the cap and tighten it securely
after inserting the fire extinguisher into
the container.
2. Reinstall the container on the hood and
secure it with the band.

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, steering pole, han-
dlebars, and jet unit with fresh water.
3. Remove the hood and check the engine
compartment for water. To drain excess
water, turn the watercraft on its port (left)
side. If necessary, turn the watercraft
upside down to drain water completely.
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 onto its
side or inverting it, support the bow
and secure the steering pole, other-
wise the steering pole and handlebars
could be bent or damaged.
@
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 pages 4-1 to 4-2 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.

Transporting
WARNING@ Always place the fuel cock knob in the
“OFF” position when transporting the
watercraft, otherwise fuel could leak out
into the engine or engine compartment,
which would create a fire hazard.
@
Transport this watercraft using the special
trailer that incorporates a hole into which the
pin 1 can be inserted and locked after
passing it through the rope hole 2.
After securing the bow with the pin,
secure the stern with ropes or tie downs 2
over the gunwale. Use a rubber shock
cord1 to hold the steering pole.
CAUTION:@
Do not route ropes or tie downs over
the steering pole, as they may damage
it. Also, wrap the ropes or tie downs
with towels or rags where they touch
the body of the watercraft to avoid
scratching or damage.

Do not transport the watercraft with
steering pole up, or the steering pole
may be damaged during transporta-
tion.
