SHUTTING DOWN THE ENGINE
(STOPPING)
Stop the engine in accordance with the following
procedures:
Normal Stopping
1. Move the control head handle to the N (Neutral)
position. (The NEUTRAL lamp will come on.)
2. Cool the engine down at low speed (below
1000 min
-1
(rpm)) for about 5 minutes.
For maximum engine life, Yanmar recommends
that when shutting the engine down, you allow
the engine to idle, without load, for 5 minutes.
This will allow the engine components that
operate at high temperatures, such as the
turbocharger and exhaust system, to cool
slightly before the engine itself is shut down.
3. Press the Engine START/STOP switch on the
switch panel of the selected station to stop the
engine.
4. Press the Power switch to turn the power OFF.
Do not press the Engine START/STOP
switch when the engine is stopped. The
engine will restart.
Do not turn the Battery switch OFF before
turning the Power switch OFF.
Wait 4 seconds or more before turning battery
switch off for secure system settle down.
5. Turn the battery switch off for engine and VC20.
6. Close the fuel tank cock.
7. Close the seacock.
Be sure to close the seacock. Neglecting
to close the seacock could allow water to
leak into the boat and may cause it to sink.
If seawater is left inside the engine, it may
freeze and damage parts of the cooling
system when the ambient temperature is
below 0 °C (32 °F).
