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 pre-mixed models
Run the engine under load (in gear with a pro-
peller 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 (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. Next two hours:
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. Remaining seven hours:
Run the engine at any speed. However,
avoid operating at full throttle for more
than 5 minutes at a time.
5. After the first 10 hours:
Operate the engine normally. Use the
standard premix ratio of gasoline and oil.
For details on mixing fuel and oil, see
page 28.
