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.

Procedure for 4-stroke models
Your new engine requires a period of 10
hours break-in to allow mating surfaces of

break-in will help ensure proper performance
and longer engine life.

TIP:
Failure to follow the break-in procedure
could result in reduced engine life or even
severe engine damage. Run the engine in
the water, under load (in gear with a propel-
ler installed) as follows. For ten hours for
breaking in engine avoid extended idling,
rough water and crowded areas.
1.
For the first hour of operation:
Run the engine at varying speeds up to
2000 r/min or approximately half throttle.
2.
For the second hour of operation:
Increase engine speed as much as nec-
essary to put the boat on plane (but
avoid full-throttle operation), then back
off on the throttle while keeping the boat
at a planing speed.
3.
Remaining eight hours:
Run the engine at any speed. However,
avoid operating at full throttle for more
than 5 minutes at a time.
4.
After the first 10 hours:
Operate the engine normally.
