Operating Procedures
BEFORE STARTING
1. Check the water level by removing the pressure
cap from the expansion tank. In order to give the
cooling water room to expand, the level should be
about 1 3/4 in. (4-5 cm) below the
fi
ller cap sealing
surface when the engine is cold. When
fi
lling with
coolant, the venting cock on top of the turbocharger
should be opened to ensure that no air pockets form
in the cooling system
(see Service Point #14)
.
CAUTION:
Use protective clothing and open
the
fi
ller cap carefully when the engine is warm
to prevent burns.
2. Check the oil level in the crankcase with the dipstick.
The oil level should be between the “waf
fl
ed area”
and the “Add”. Never allow the level to go below
the “Add”. Do not
fi
ll above the crosshatch pattern.
Oil levels within the crosshatch are considered in the
acceptable operating range. Always add the same
viscosity of oil as is already in the crankcase
(see
Service Point #1)
.
3. Check the fuel tank level and open any fuel valves.
4. Check the oil level in the reverse gear. Methods
may vary from gear to gear. See your Gear Owner's
Manual.
5. Close the seacock, check and clean the strainer and
reopen the seacock.
6. Place the battery switch in the ON position.
NOTE:
The battery switch must always be kept ON
while the engine is running. If the switch is turned
OFF while the engine is running, the battery charging
regulator could be ruined.
Starting
1. Put the gear control in the neutral position.
2. Move the throttle control to the idle position.
3. Turn the key switch to the
fi
rst position. Check the
voltage meter to see the condition of the batteries.
For starting, the voltmeter should not read below 12
volts (24 volts for 24 volt systems).
4. Turn the key to the starting position and as soon as
the engine starts, release the key. Move the throttle
up until the engine is running at approximately 1000
RPM.
5. Do not crank the starter for more than 15 seconds
consecutively. If the engne fails to start with the
fi
rst
attempt, be sure that the starter has stopped com-
pletely before re-engaging.
NOTE
:
Never race a cold engine. Operate at 1000
RPM for a 3 to 5 minute warm-up period.
Operating
1.
Check oil pressure as soon as the engine has started.
Oil pressure should be above 15 PSI. The engine
must never be run if the oil pressure is below 15 PSI.
2. Check the voltmeter. It should read 13 to 14 volts
(26-28 volts, 24 volt systems) at 60
0
F (16
0
C).
3. Water temperature should not rise over 200
0
F (94
0
C).
If it does, shut down the engine and investigate the
cause of overheating.
4. Do not exceed 800 RPM when shifting marine gear.
Repeated shifts at higher engine speeds can damage
the reverse gear.
5. Low idle is 650 RPM. Maximum working engine
speed is: 2100 RPM for High Output, 1900 RPM for
Medium Duty, and 1800 RPM for Continuous Duty.
6. If the proper propeller is used, the engine should
reach its appropriate maximum RPMs at full throttle.
If the maximum rated RPMs for your engine applica-
tion is exceeded at full throttle, then your propeller is
too small. If you cannot reach your maximum rated
RPMs at full throttle, either your propeller is too large
or bottom growth is slowing the boat.
7. To establish Maximum Cruising RPM: Establish the
RPM at full throttle and subtract 200-300 RPM. This
will promote engine life and reduce fuel consumption.
Shutdown
1. Run engine three to
fi
ve minutes in neutral at 1000
RPM, for cool down period.
2. Return engine to low idle.
3. Turn the key switch counterclockwise as far as pos-
sible to stop the engine.
4. Close the sea cock and fuel valves and put the battery
switch in OFF position.
NOTE:
Do not turn the battery switch to OFF while
the engine is running.
ALARMS
1. Your unit is
fi
tted with a warning system to indicate
high water temperature or low oil pressure.
Propulsion engines have warning horns to sound and
warn you of a problem. Remember- when the engine
is not running the horn will sound when the key is in
the "ON" position because there is no oil pressure.
