Operation and handling requirements
53
To check the engine oil level:
(1) With the engine stopped, place the wa-
tercraft in a precisely level position on
land or launch the watercraft.
(2) Look in all directions, and then start the
engine. (See page 68 for information on
starting the engine.)
(3) Run the engine at idling speed for 6 mi-
nutes or more. Run the engine an addi-
tional 5 minutes if the ambient
temperature is 20 °C (68 °F) or less.
(4) Stop the engine.
(5) Remove the seats. (See page 43 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
filler cap again and make sure that theengine 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 seats in their original
positions.

Engine break-in
NOTICE
ECJ00432
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 52
for information on checking the engine
oil level.)
(2) Launch the watercraft and start the en-
gine. (See page 68 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.
