fore first-time operation to avoid severe
engine damage.

Breaking in engine
Your new engine requires a period of break-in
to allow mating surfaces of moving parts to
wear in evenly. Correct break-in will help en-
sure proper performance and longer engine
life. NOTICE: Failure to follow the break-in
procedure could result in reduced engine
life or even severe engine damage.

gine avoid extended idling, rough water and
crowded areas.
