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 52
for information on checking the engine oil
level.)
(2) Launch the watercraft and start the en-
gine. (See page 67 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 30 minutes, operate with the
engine speed below 5000 r/min.
(5) For the next 1 hour, operate with the en-
gine speed below 6000 r/min.
After the engine break-in is complete, the wa-
tercraft can be operated normally.
