Operation
ECM01630
CAUTION:
During water testing, check the buoy-
G
ancy of the boat, at rest, with its maxi-
mum load. Check that the static water
level on the exhaust housing is low
enough to prevent water entry into the
power head when water rises due to
waves when the outboard is not run-
ning.
Incorrect engine height or obstructions
G
to the smooth flow of water (such as the
design or condition of the boat, or ac-
cessories such as transom ladders or
depth finder transducers) can create
airborne water spray while the boat is
cruising. If the motor is operated con-
tinuously in the presence of airborne
water spray, enough water could enter
the engine through the intake opening
on the cowling to cause severe engine
damage. Eliminate the cause of the air-
borne water spray.

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.

CAUTION:
Failure to follow the break-in procedure
G
could result in reduced engine life or
even severe engine damage.
Premix fuel must be used during break-
G
in in addition to oil in the oil injection
system.

Procedure for oil injection models
Run the engine under load (in gear with a
propeller installed) for 10 hours as follows.
1.
First 10 minutes:
Run the engine at the lowest possible
speed. A fast idle in neutral is best.
2.
Next 50 minutes:
Do not exceed half throttle (approxi-
mately 3000 r/min). Vary engine speed
occasionally. If you have an easy-plan-
ing boat, accelerate at full throttle onto
plane, then immediately reduce the
