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) Fill the fuel tank with fuel in a fuel-to-oil ra-
tio of 25:1. (See page 31 “Mixing fuel and
oil” and “Filling the fuel tank” for fuel filling
procedures.)
(2) Launch the watercraft and start the en-
gine. (See page 45 for engine starting
procedures.)
(3) For the first 5 minutes, operate with the
engine at idling speed.
(4) For the first tankful of fuel, squeeze the
throttle lever slowly and operate at 3/4
throttle or less.
(5) Fill the fuel tank once more with fuel in a
fuel-to-oil ratio of 25:1, and then operate
with the engine at any speed.
After completing the engine break-in, fill the
fuel tank with fuel in a fuel-to-oil ratio of 50:1
and proceed with normal operation.
