STARTING/STOPPING
PROCEDURE
STARTING
PROCEDURE
Place the transmission in neutral and advance the throttle
control to slightly open.
A
CAUTION:
Make
certain
the
transmission
is
in
neutral.
Starting
in
gear
could
result
in
serious
damage
to
your
transmission,
your
boat,
and
vessels
nearby.
Tum
the
KEY
SWITCH to the
ON
position (2
0'
clock)
PREHEAT:
Depress the PREHEAT switch.
The
voltmeter,
panel lights, gauges and meters, and fuel solenoid will be
activated. The
PREHEAT
switch should be depressed in
accordance with the following chart:

START:
While still depressing the PREHEAT switch, de-
press the
START
switch. This will engage the start sole-
noid. Upon engine firing, release the
START
switch.
Do
not release the PREHEAT switch until the oil pressure
reaches
15
psi. Then as long as the high water tempera-
ture and low oil pressure protective circuits do not
acti-
vate, the engine will remain energized and continue
to run.
NOTE:
When starting:
A voltage drop will occur
when the preheat switch
is depressed.
Should the engine not start when the
START
switch is
depressed for
10 to 20 seconds, release both switches and
wait
30 seconds; repeat the procedure above and preheat
longer.
Never
run
the
starter
for
more
than
30
seconds.
A
CAUTION:
Prolonged
cranking
intervals
without
the
engine
starting
can
result
in
the
engine
exhaust
system
filling
with
raw
water.
This
may
happen
be-
cause
the
pump
is
pumping
raw
water
through
the
raw
water
cooling
system
during
cranking.
This
raw
water
can
enter
the
engine's
cylinders
by
way
of
the
exhaust
manifold
once
the
exhaust
system
fills.
Pre-
vent
this
from
happening
by
closing
the
raw
water
supply
through-hull
shut-off,
draining
the
exhaust
muffler,
and
correcting
the
cause
of
the
excessive
engine
cranking.
Engine
damage
resulting
from
raw
water
entry
is
not
a
warrantable
issue;
the
owner/operator
should
keep
this
in
mind.
Once the engine starts, check instruments for proper oil
pressure and battery charging voltage.
NOTE:
Never attempt to engage the starter while the
engine is running.
NOTE:
Some unstable running may occur in a cold engine.
Depressing the Preheat switch
for
10-15 second intervals
will help stabilize the engine
RPM
until the operating tem-
perature reaches 170°-190°F (77°-88°C) and a propeller
load is applied
to
the engine. When the engine is running
and
the
preheat
switch is depressed, a charging load on
the
DC
alternator will be discernible.
STARTING
UNDER
COLD
CONDITIONS
Make certain the lubricating oil conforms with the ratings for
the prevailing temperature. Check the table
on
the engine
oil section
of
this manual.
The
battery should be fully charged to minimize voltage
drop.
Use a sufficient amount
of
preheat to aid in starting.
See TemperaturelPreheat chart on this page.
STOPPING
PROCEDURE
To
stop the engine, bring the throttle to an idle position
and place the transmission in neutral. Allow the engine to
idle for a few moments to stabilize temperatures.
Tum
the key to the
OFF
position. This opens the DC circuit to
the instrument panel and engine, de-energizing the fuel
solenoid
on
the injection pump, stopping fuel flow from
it and stopping the engine.
Made certain the key switch is in the
OFF
position
(12 o'clock).
If
the Key Switch is left ON, the battery
will discharge.
An
engine alarm buzzer is provided to
warn the operator
of
this condition (Key Switch ON).
The
best method
of
preventing the battery from discharge
is to remove the key from the Key
Switch after stopping
the engine.
