ENGINE
BREAK-IN
PROCEDURE
DESCRIPTION
Although your engine has experienced a minimum
of
one
hour
of
test operations at the factory to make sure accurate
assembly procedures were followed and that the engine oper-
ated properly, a break-in time is required. The service life
of
your engine
is
dependent upon
how
the engine is operated
and serviced during its initial
50
hours
of
use.
Breaking-in a new engine basically involves seating the pis-
ton rings to the cylinder walls. Excessive oil consumption
and smoky operation indicate that the cylinder walls are
scored, which is caused by overloading the engine during the
break-in period.
Your new engine requires approximately
50
hours
of
initial
conditioning operation to break in each moving part in
order
to maximize the performance and service life
of
the engine.
Perform this conditioning carefully, keeping
in
mind the fol-
lowing:
1. Start the engine according to the
STARTING PROCE-
DURE
section. Run the engine at fast idle while checking
that all systems (raw water
pump,
oil pressure, battery
charging) are functioning.
2. Allow the engine to warm up (preferably by running at
fast idle) until the water temperature gauge moves into
the
130 - 140°F (55 - 60°C) range.
3. While using the vessel, run the engine at various engine
speeds for the first 25 hours. Avoid prolonged periods
of
idling.
4. Avoid rapid acceleration, especially with a
cold
engine.
5.
Use caution not to overload the engine. The presence
of
a
grey
or
black exhaust and the inability
of
the engine to
reach its full rated
speed
are signs
of
an
overload.
6. During the next 25 hours, the engine may be operated at
varying engine speeds, with short runs at full rated rpm.
Avoid prolonged idling during this break-in period.
CHECK
LIST
o Monitor the control panel gauges.
o Check for leaks
of
fuel and engine oil.
o Check for abnormal noise such as knocking, friction.
vibration and blow-back sounds.
o Confirm exhaust smoke:
When the engine is
cold
- white smoke.
When the engine is
warm
- almost smokeless.
When the engine
is
overloaded - some black smoke and soot.
