ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
NOTICE
ECJ01001
Make sure that debris and water do not en-
ter the oil 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 precisely level
position on land with the engine stopped.

tween the minimum and maximum level
marks.
(4) If the engine oil level is below the mini-
mum level mark, perform steps 5–7 to
add enough oil so that the oil level is be-
tween the minimum and maximum level
marks on the dipstick. If the engine oil lev-
el is significantly above the maximum lev-
el mark, have a Yamaha dealer service
the watercraft.(5) Remove the engine oil filler cap.
(6) Pour engine oil into the filler hole. Wait
approximately 5 minutes until the engine
oil settles.

watercraft.
EJU36661Engine break-in
NOTICE
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
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.
TIP:
Be sure to check the engine oil level before
operating the watercraft for the first time. (See
page 52 for engine oil checking procedures.)
(1) Launch the watercraft and start the en-
gine. (See page 60 for engine starting
procedures.)
(2) For the first 5 minutes, run the engine at
trolling speed only. For the 30 minutes of
operation after that, keep the engine
speed below 5000 r/min. For the 1 hour of
operation after that, keep the engine
speed below 6000 r/min.
(3) Proceed with normal operation.
