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. If tem-
porarily leaving the watercraft with a
full fuel tank, do not leave it in direct
sunlight. Leave it in a well-ventilated
area with the watercraft in a horizontal
position.

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:@
Do not use leaded gasoline. Leaded
gasoline can seriously damage the
catalytic converter.

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)

Bilge
Check for moisture and fuel residue in the
bilge.
This watercraft is equipped with a conven-
tional jet vacuum bilge draining system and
an electric bilge draining system. The elec-
tric bilge draining system is operated when
the engine is running. When excess water
reaches the water inlet of the electric bilge
pump, the water is discharged via the
exhaust passage from the jet thrust nozzle.
A small quantity of water will remain in the
bilge and should be removed manually. To
remove any residual water, perform the fol-
lowing procedure.
To remove water from the bilge:
1. Remove the stern drain plugs.
2. Raise the bow of the watercraft until the
water drains.
3. After the water has drained, wipe the
bilge with dry rags to make sure that the
bilge is thoroughly dry.
4. Install the drain plugs.
CAUTION:@
Make sure that the stern drain plugs
are tightened securely before launch-
ing the watercraft.

Clean any foreign materials, such as
dirt or sand, from the drain plug
threads before installing the drain
plugs.
