BEFORE YOU OPERATE
50 6LY3 Operation Manual
CRANKING
When the engine has not been used for a
long period of time, engine oil will not be
distributed to all of the operating parts.
Using the engine in this condition will lead
to seizure.
After a long period of no use, distribute
engine oil to each part by cranking.
Perform in accordance with the following
procedures before beginning operation.
1. Open seacock.
2. Open fuel tank cock.
3. Put remote control lever (Figure 8, (1))
in NEUTRAL (Figure 8, (2)). See
Starting the Engine on page 64.
Figure 8
4. Press the battery switch.
5. Hold the stop lever of the governor to
the stop position (gear case side) to
stop fuel injection.
6. Turn the start switch to the ON position.
7. Push and hold the start switch for 15
seconds (cranking). Release the start
switch and the engine stops. Wait for
15 seconds and repeat again for 15
seconds. This will distribute oil to the
lubricated parts.
8. Push the SELECT button then push the
N button and the N lamp flashes. Push
the start switch to start the engine.
Release the switch when the engine
has started. Raise the engine speed
gradually and check for abnormal
sounds. Also check that sufficient
seawater is being discharged from the
outlet and that the color of the exhaust
gas is normal. When you raise the
engine speed, more coolant should be
discharged from the outlet.
When engine coolant is supplied for the
first time or when it must be replaced,
conduct a trial operation of the engine for
about 5 minutes and check the quantity of
lubricating oil and coolant.
