WARNING
Avoid using bolts, nuts or washers other
than those contained in the engine pack-
aging. If used, they must be of at least the
same quality of material and strength and
must be tightened securely. After tighten-
ing, test run the engine and check their
tightness.

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
could result in reduced engine life or even
severe engine damage.

Procedure for pre-mixed models

Run the engine under load (in gear with a pro-
peller installed) 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 (approximate-
ly 3000 r/min). Vary engine speed occa-
sionally. If you have an easy-planing
boat, accelerate at full throttle onto plane,
then immediately reduce the throttle to
3000 r/min or less.
3. Second hour:
Accelerate at full throttle onto plane, then
reduce engine speed to three-quarter
throttle (approximately 4000 r/min). Vary
engine speed occasionally. Run at full
throttle for one minute, then allow about
10 minutes of operation at three-quarter
throttle or less to let the engine cool.
4. Third through tenth hours:
Avoid operating at full throttle for more
than 5 minutes at a time. Let the engine
cool between full-throttle runs. Vary en-
gine speed occasionally.
5. After the first 10 hours:
Operate the engine normally. Use the
standard premix ratio of gasoline and oil.
