STARTING/STOPPING

PROCEDURE

STARTING

PROCEDURE

Place the transmission in neutral and advance the throttle

control to slightly open.

CAUTION:

Make

certain

the

transmission

neutral.

Starting

gear

could

result

serious

damage

your

transmission,

your

boat,

and

vessels

nearby.

Tum

the

KEY

SWITCH to the

position (2

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.

not release the PREHEAT switch until the oil pressure

reaches

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

than

seconds.

CAUTION:

Prolonged

intervals

without

can

issue;

the

owner/operator

should

keep

this

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

the engine. When the engine is running

and

the

preheat

switch is depressed, a charging load on

the

alternator will be discernible.

STARTING

UNDER

COLD

CONDITIONS

Make certain the lubricating oil conforms with the ratings for

the prevailing temperature. Check the table

the engine

oil section

this manual.

The

battery should be fully charged to minimize voltage

drop.

Use a sufficient amount

preheat to aid in starting.

See TemperaturelPreheat chart on this page.

STOPPING

PROCEDURE

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

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).

the Key Switch is left ON, the battery

will discharge.

engine alarm buzzer is provided to

warn the operator

this condition (Key Switch ON).

The

best method

preventing the battery from discharge

is to remove the key from the Key

Switch after stopping

the engine.
