Pre-operation check points
EJU32310
Engine compartment
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, remove
the seat. (See page 28 for seat removal and
installation procedures.) 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.
EJU32350
Hull and deck
Check the hull and deck for cracks and other
damage. If any damage is found, have a
Yamaha dealer repair the watercraft.
EJU32390
Fuel level
Check the fuel system for leakage, cracks,
and malfunctions before each use. (See page
75 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. (See page 28 for seat
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 44 for
filling procedures.)
(4) Install the fuel tank filler cap and the seat.
EJU32400
Engine oil level
Check the engine oil level before each use.
CAUTION:
ECJ00390
When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, and obstacles. The
water current and wind can cause the
watercraft to move and lead to a colli-
sion.
When checking the engine oil level on
land, supply water to the cooling water
passages. (See page 68 for procedures
on supplying water.)
Make sure that the engine has enough
oil, but do not overfill it. If there is too lit-
tle oil, the engine can be damaged. If
there is too much oil, the air filter can be-
come saturated with oil, permanently
damaging the filter and reducing engine
performance. Follow the checking pro-
cedure carefully.
Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
To check the engine oil level:
(1) Place the watercraft in a horizontal posi-
tion or launch the watercraft, and then
start the engine.
(2) Run the engine at trolling speed for 6 min-
utes or more, and then stop the engine.
