STOPPING PROCEDURES
In
the cockpit
of
the boat, there
Is
a tee handle
or
a knob-type shut-of control. When this control is pulled
OUTWARD, the control will
STOP the engine. The other end
of
the shut-off control is attached
to
a lever on
the
top
of
the fuel Injection pump. (Pushing the shut-off control fully inward will place the engine in the
RES-
TART - RUN position.
When the engine
is
stopped, turn the Circuit Breaker located in the vessel
to
the OFF position. If the Circuit
Breaker is left
ON, the battery will discharge.
CAUTION
DO
NOT attempt
to
shutdown the engine
by
turning the
Circu~
Breaker OFF. The Circuit
Breaker only provides power to the instrument panel and to the
DC alternator: the engine will
continue running even if the Circuit Breaker is turned
OFF. Stop the engine
by
pulling the
shut-off control fully
OUTWARD.

Break-In
Procedures
Although your engine has experienced a minimum
of
one hour
of
test operations
to
ensure accurate as-
sembly and proper operation
of
all systems, break-in time is required. The service life
of
your engine is de-
pendent upon
how
the engine is operated and serviced during
~s
initial hours
of
use.
Your new engine requires approximately
50
hours
of
In~ial
conditioning operation
to
break
In
each moving
part in order
to
maximize the performance and service life of the engine. Perform this conditioning careful-
ly, keeping in mind the following:
1.
Start the engine according
to
the "STARTING PROCEDURE" section found on page 26; run the engine
at fast idle while checking that all systems (sea water pump, oil pressure, battery charging) are function-
ing.
2.
Allow the engine
to
warm up (preferably
by
running at fast idle) until the watertemperature gauge moves
into the t
30-140° F range.
3.
While using the vessel under power, vary the engine's rpm cruise settings during the engine's initial
25
hours
of
operation.
4.
Avoid rapid acceleration, especially with a cold engine.
5.
Use caution not
to
overload the engine. The presence
of
a gray
or
black exhaust, and the inability
of
the engine
to
reach its full rated speed, are signs of an overload (that
is,
a propeller that is too large).
6.
During the next 25 hours, the engine may be operated at varying engine speeds, with short runs at full
rated rpm. Avoid idling the engine for prolonged periods of time.
Breaking-in a new engine basically involves seating the piston rings to the cylinder walls. This cannot be ac-
complished
by
long periods
of
running at Idle, nor by early running at full speed.
Idle running may glaze the cylinder walls, resulting in excessive oil consumption and smoky operation. Ex-
cessive speed
or
heavy overloading, especially with a cold engine, may cause scoring
of
the cylinder walls,
producing similar results.
