Operation and handling requirements
46
To check the engine oil level:
(1) With the engine stopped, place the water-craft in a precisely level position on land
or launch the watercraft.
(2) Look in all directions, and then start the engine. (See page 60 for information on
starting the engine.)
(3) Run the engine at idling speed for 6 min- utes or more. Run the engine an addition-
al 5 minutes if the ambient temperature is
20 °C (68 °F) or less.
(4) Stop the engine.
(5) Remove the seat. (See page 38 for seat removal and installation procedures.)
(6) Loosen the oil tank filler cap and remove it, and then wipe the attached dipstick
clean.
(7) Screw the oil tank filler cap into the filler hole until it stops. Remove the oil tank fill-
er cap again and make sure that the en- gine oil level is between the minimum and
maximum level marks.
(8) If the engine oil level is significantly above the maximum level mark, consult a
Yamaha dealer. If the engine oil level is below the minimum level mark, slowly
add engine oil.
(9) Repeat steps 6–8 until the engine oil is at the proper level.
(10) Securely install the oil tank filler cap and turn it until it stops.
(11) Securely install the seat in its original po- sition.

Engine break-in
NOTICE
ECJ00431
Failure to perform the engine break-in
could result in reduced engine life or even
severe engine damage.
The engine break-in is essential to allow the
various components of the engine to wear
and polish themselves to the correct operat-
ing clearances. This ensures proper perfor-
mance and promotes longer component life.
To perform the engine break-in:
(1) Check the engine oil level. (See page 45for information on checking the engine oil
level.)
(2) Launch the watercraft and start the en- gine. (See page 60 for information on
starting the engine.)
(3) For the first 5 minutes, operate with the engine at idling speed.
(4) For the next 30 minutes, operate with the engine speed below 5000 r/min.
(5) For the next 1 hour, operate with the en- gine speed below 6500 r/min.
After the engine break-in is complete, the wa-
tercraft can be operated normally.

EJU32333Engine compartment check
WARNING
EWJ00461
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.
Ventilate the engine compartment. Leave the
engine compartment open for a few minutes
to allow any fuel vapors to escape.
Make sure that there is no damage inside the
engine compartment.

WARNING
EWJ00381
Leaking fuel can result in fire or explosion.
●Check for fuel leakage regularly.
●If any fuel leakage is found, the fuel sys-
tem must be repaired by a qualified me-
chanic. Improper repairs can make the
watercraft unsafe to operate.
Make sure that there is no damage, leakage,
or other problem in the fuel system.
Check:
●Fuel filler cap and seal for damage
●Fuel tank for damage and leakage
●Fuel hoses and joints for damage and leak-
age
