Break-in procedure
Run the engine under load (in gear with a
propeller 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 (approxi-
mately 3,000 r/min). Vary engine
speed occasionally. If you have an
easy-planing boat, accelerate at full
throttle onto plane, then immediately
reduce the throttle to 3,000 r/min or
less.
3)
Second hour:
Accelerate at full throttle onto plane,
then reduce engine speed to three-
quarter throttle (approximately 4,000
r/min). Vary engine speed occasional-
ly. Run at full throttle for one minute,
then allow about 10 minutes of opera-
tion 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 engine speed occasionally.
For premix models
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 “Gasoline and oil mixing” in this
chapter.

Make sure to mix gasoline (petrol) and oil
completely, otherwise your outboard
motor may be damaged.
