EMU27090

Procedure for HPDI models

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 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
throttle to 3000 r/min or less.
3.
Second hour:
Accelerate at full throttle onto plane,
then reduce engine speed to three-quar-
ter 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-
31
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.
