EJU32280Pre-operation check points EJU32300Engine compartment
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, remove
the seat and front storage compartment. (See
“Seat” on page 21 and “Front storage com-
partment” on page 32 for more information.)
Leave the engine compartment open for a few
minutes to allow any fuel vapors to escape.
While the engine compartment is open, check
for loose electrical connections.
WARNING
EWJ00460
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak or
a loose electrical connection.
EJU32350Hull and deck
Check the hull and deck for cracks and other
damage. If any damage is found, have a
Yamaha dealer repair the watercraft.
EJU32371Fuel and oil systems
Check the fuel system for leakage, cracks,
and malfunctions before each use. (See page
66 for check points and correct procedures.)
(1) Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.(2) Remove the seat and front storage com-
partment. (See “Seat” on page 21 and
“Front storage compartment” on page 32
for more information.)
(3) Check the fuel and oil levels in the tanks
and replenish if necessary. (See page 36
for refueling procedures and page 36 for
oil tank filling procedures.)
(4) Install the fuel tank filler cap, seat, and
front storage compartment.
EJU32420Water separator
Check the water separator for water. The wa-
ter separator retains any water that may have
entered through the fuel tank breather hose if
the watercraft was capsized. Normally, the
water separator is empty.
If water remains in the water separator, drain
it by removing the drain screw. Place a drain
pan under the water separator to catch the
draining water or use a dry cloth to soak up
any water that could spill into the watercraft. If
any water spills into the watercraft, be sure to
wipe it up with a dry cloth. Also, be sure to in-
stall the drain screw after draining the water
separator.
EJU32440Bilge
Check the bilge for moisture and fuel residue.

Operation
WARNING
EWJ00510
Before operating your watercraft, become
familiar with all of the controls. Consult a
Yamaha dealer about any control or func-
tion that you do not fully understand. Fail-
ure to understand how the controls work
could cause an accident or prevent you
from avoiding an accident.
CAUTION:
ECJ00460
Make sure that the stern drain plugs are
tightened securely before launching the
watercraft.
EJU32760Engine break-in
The engine break-in period is essential to al-
low the various components of the engine to
wear and polish themselves to the correct op-
erating clearances. This ensures proper per-
formance and promotes longer component
life.
CAUTION:
ECJ00450
For the first tankful of fuel, premix the
fuel in a fuel-to-oil ratio of 50:1 (in addi-
tion to the oil in the oil tank).
After break-in, use straight gasoline for
normal operation.

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. If tempo-
rarily leaving the watercraft with a full
fuel tank, do not leave it in direct sun-
light. Leave it in a well-ventilated area
with the watercraft in a horizontal posi-
tion.
