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 posttion.
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 Circutt Breaker OFF. The Circutt
Breaker only provides power
to
the instrument panel and
to
the
DC
alternator: the engine will
continue running even H 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 its initial hours
of
use.
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 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 water temperature gauge moves
into the
130-140' 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.
