JH Series Operation Manual
SHUT-DOWN THE ENGINE
(STOPPING)
Stop the engine in accordance with the
following procedures:
Normal Stopping
1. Move the remote control 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.
NOTICE
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 turbo-charger 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.
4. Press the Power switch and turn the
power OFF.
CAUTION
Do not press the Engine START/STOP
switch when the engine is stopped.
The engine will restart.
5. Wait 6 seconds or more before turning
the battery switch off for secure system
settle down.
NOTICE
• Do not turn the battery switch off
before turning the power switch off or
immediately after turning off the power
switch.
• Turning the battery switch off before
secure system settle down may cause
alarm to be set at the next activation by
turning on the power switch. In an
emergency situation, you can start the
engine even if the alarm is set.
In order to release above alarm, turn
off the power switch and wait 6
seconds before turning the power
switch on again.
6. Turn the battery switch off for engine
and engine control system.
7. Close the fuel tank cock.
8. Close the seacock.
CAUTION
• 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).
