Engine break-inECJ00432
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 61 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.

EJU36943Engine oil and oil filterEWJ00341
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.

Do not run the engine with too much or not
enough oil in the engine, otherwise the en-
gine could be damaged.
It is recommended to have a Yamaha dealer
change the engine oil and the engine oil filter.
However, if you choose to change the oil and
filter on your own, consult a Yamaha dealer.
