Proper Engine Break-In
CAUTION First twenty-five (25) hours vary the RPM. Avoid
sustained periods of wide open throttle. Some EFI engines
will not reach WOT until engine is up to normal operating
temperatures.
AT NO TIME SHOULD THE ENGINE BE OPERATED
BEYOND THE SPECIFIED MAXIMUM RPM RATING.
FAILURE TO ADHERE TO THERE RECOMMENDATIONS
WILL VOID THE TERMS OF WARRANTY.
To insure maximum life of your MARINE POWER engine, the
following engine break-in schedule is recommended:
First hour - Perform sea trial.
IMPORTANT! During the break-in period, pay close attention
to the following steps.
1. OIL LEVEL: Check the oil level before each engine start
up and every eight (8) hours of continuous operation. It
should be understood that internal combustion engines
will use a certain amount of oil during operation as a
cooling and lubricating agent (especially during break-in
period). Oil consumption should decrease after approxi-
mately 100 hours of operation.
IMPORTANT! The space between "FULL" and "ADD" marks
on the dipstick represent one quart. It is not necessary to add

oil unless the level is at or below the "ADD" mark.
CAUTION Engine dipstick level may change due to the angle
of installation. Ensure that "high" oil level is properly marked
accordingly.
CAUTION When adding crankcase oil, DO NOT OVERFILL. If
crankcase is overfilled, it will cause foaming or aeration of oil
in the oil pan. This will effect oil pressure which may result in
severe internal engine damage.
2. VOLTMETER: Normal reading is 13.0 - 14.5 volts at 2,000
RPM.
3. OIL PRESSURE: Not less than 10 PSI at idle.
4. NORMAL OPERATING TEMP: Raw water cooling - less
than 165 degrees. Closed cooling - between 160 and 190
degrees.
5. IDLE RPM: Normal reading is 650 - 800 RPM in gear.
Note: For Jetpac applications, normal reading is 800 -
1,000 RPM.
6. THROTTLE AND SHIFT CONTROLS: Check that movement
is not constrictive. Verify that linkage is adjusted so that
engine may reach Wide Open Throttle (WOT).
7. EXHAUST, OIL, WATER AND FUEL SYSTEM: Inspect for
leaks. Be sure to check riser bolt tightness after 10 hours
and every 50 hours of operation. Refer to Maintenance
Schedule.
It is very important to re-tighten exhaust manifold riser
bolts after 10 hours of operation. Failure to do so can cause
non-warrantable engine damage.

General Information

ENGINE ROTATION
Directional references used in this section are given as if
standing behind the boat, looking forward:
• Front of boat is bow.
• Rear of boat is stern.
• Right side is starboard.
• Left side is port.
The raw water (or seawater) pump is located at the front of
the engine on the crankshaft pulley. Engine rotation can be
determined by looking at the stern end of the engine and
observing the flywheel rotation. Do not assume engine
rotation by looking at the propeller rotation; it may not be the
same. This information is critical when ordering parts for your
engine.
Left Hand Engines: CCW or Normal Rotation Right Hand
Engines: CW or Opposite Rotation.
PROPELLER WARNING
WARNING! MARINE POWER does not warranty items
damaged due to detonation. The propeller selected should
allow the engine to operate at or near the recommended
wide open throttle RPM range with a normal load. Wide Open
Throttle RPM range is listed in Engine Identification Section.
