STARTING/STOPPING PROCEDURE
ELECTRIC STARTING
The
7A-I/llA-1
diesel engine has a 12 VDC electric starter. The
engine is started by using a keyswitch on the control panel. The
switch has
three
positions: OFF, ON and START.
NOTE:
Periodically lubricate the keyswitch mechanism with
LOCKEZE to ensure proper keyswitch functioning.

KEYSWITCH
1. Place the transmission in neutral and advance the throttle con-
trol to slightly open.
A
CAUTION:
Make certain the transmission is in neu-
tral. Starting in gear could result in serious damage
to
your transmission, your boat, and vessels nearby.
2. Turn the keyswitch to the ON position. The alann buzzer on
the control panel will beep. Push the key in to preheat. Hold
the key in and
turn
it
to
the START position. When the
engine starts, let go of the key and it will come out of preheat
and spring back to the ON position (observe that it does this).
NOTE:
If
the engine doesn
~
start, limit each starting trial to
10-
20 seconds. Wait for approx. 30 seconds before repeating the
start. Never operate the starter motor while the engine
is
still
running.
NOTE:
Some unstable running
may
occur in a cold engine.
This
condition should smooth out as the nOf77Ul1 operating temperature
is reached and a load is applied. Allow a few minutes for the
wann-up
at
a comfortable rpm (approximately 1,000 rpm), then
reduce the rpm and get underway.
Low Battery Electric Starting Procedure
If the battery is discharged and too low for a normal electric start
but not completely
dead,
an attempt at an electric start can be
made by using the Automatic Decompression Device. This device
works by holding the exhaust valve open, and is normally used
when manually starting (hand-cranking) the engine.
NOTE:
The Automatic Decompression Device
is
not used for
nOf77Ul1 electric starting. During engine operation, the pointer on
this device
is
in the operating
(9
o'clock) position.
1. Place the transmission in neutral and advance the throttle con-
trol to slightly open.
2. Using a IOmm wrench,
turn
the hex-head bolt on the
device so the pointer is in the manual starting position
(see illustration).

3. Turn the keyswitch to the START position. The alann on the
control panel will beep until the engine oil pressure comes up.
The pointer on the Automatic Decompression Device will
automatically move clockwise with each crank. The pointer
will stop at the 9 o'clock position and compression will occur
after 8 cranks. Hold the keyswitch in the START position
until either the engine starts or the pointer stops after the 8th
crank. Then let go of the key and it will spring back to the
ON position.

If this attempt at an electric start does not start the engine, then a
manual start by hand-cranking will be necessary.
MANUAL STARTING (HAND CRANKING)
When installing the engine, it is important to provide enough
space at the front end to allow for manual starting (hand cranking)
in case of an emergency or when the starting battery has become
too low to allow an electrical start.
