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.
EMU27084
Procedure for 4-stroke models
Your new engine requires a period of 10
hours break-in to allow mating surfaces of
moving parts to wear in evenly. Correct 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 propeller installed)
as follows. For ten hours for breaking in en-
gine 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:
