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 57for information on checking the engine
oil level.)
(2) Launch the watercraft and start the en- gine. (See page 72 for information on
starting the engine.)
(3) For the first 5 minutes, operate with the engine speed at 2000 r/min.
(4) For the next 90 minutes, operate with the engine speed below 5000 r/min.
After the engine break-in is complete, the wa-
tercraft can be operated normally.
