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 filler cap sealing
surface when the engine is cold. When filling 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 filler 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 “waffled area”
and the “oo”. Never allow the level to go below
the “oo”. 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 full speed position
and return back to idle.
3. Turn the key switch to the first 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 engine fails to start with the first
attempt, be sure that the starter has stopped
completely 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°F (16°C).
3. Water temperature should not rise over 200°F (94°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.
