STARTING 
PROCEDURE 
1. 
Depress 
and 
hold the preheat switch.  Preheat according to the following chart. 
2.  While still depressing the 
PREHEAT switch, depress the START switch.  As soon as the engine runs, 
release the START switch but continue to  hold the 
PREHEAT switch depressed for an additional  2  - 3 
seconds.  This allows the engine to build 
up 
enough oil pressure to close the oil pressure shutdown switch 
and 
allow the engine to continue to run. 
NOTE:  Should the engine not start when the START switch is depressed for 
10 
-
12 
seconds, 
release both switches and wait 
30 seconds; repeat the previous procedure.  Never run the starter 
motor for more 
than 
30 seconds 
at 
a time. 
3.  Check all instruments on the panel for proper operation.  Make sure raw water discharges with the 
exhaust discharge.

Limit 
of 
continuous use 
Once  the  engine  starts, allow  it to  run  for a  few 
minutes to warm up and stabilize while the engine's 
instruments are checked for  proper oil  pressure and 
battery charging voltage.  Never  attempt  to  engage 
the 
starter while the engine is running. 
NOTE:  Some unstable running may occur 
in 
a  cold  engine, 
but 
this  condition  should 
smooth  out as  the  operating  temperature 
of 
130 - 150
0 
F (55 - 56
0 
C) is reached. 
Proper glow plug function is indicated by a voltmeter 
drop when the 
PREHEAT switch is depressed.  This 
drop  will  be  slight  but  discernible. 
If 
no voltage 
drop is noted, 
it 
may indicate defective glow plugs or 
a faulty preheat circuit (check for loose connections).

II 
CAUTION 
II 
Prolonged cranking intervals without the engine starting can result 
in 
filling the engine-mounted exhaust 
system  with  sea water  coolant.  This may  happen because the  sea  water  pump  is  pumping  sea water 
through the sea water cooling system during cranking.  This sea water can enter the engine's cylinders by 
way 
of 
the exhaust manifold once the exhaust system fills.  Prevent this from happening by closing the sea 
water  supply  through-hull  shut-off, drain  the exhaust  muffler, and correct  the  cause  for the  excessive 
engine cranking needed to obtain a start.  Engine damage resulting from this type 
of 
sea water entry is not 
a warrantable issue; the owner/operator should keep this 
in 
mind.
