SHUTTING DOWN THE
ENGINE
Stop the engine in accordance with the
following procedures:
Normal Shutdown
1. Return the control lever to NEUTRAL
position. (The N light turns on.)
2. Cool the engine down at low speed
(below 1000 rpm) for about 5 minutes.
CAUTION! 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 (if equipped) and
exhaust system, to cool slightly
before the engine itself is shut down.
3. Push OFF (bottom half) of Eng ON switch
(Figure 6, (3)). The engine shuts down
within 2 to 7 seconds normally. The
regular engine shutdown takes time
because the controller is adjusted in the
fuel injection timing to the most suitable
position for the next start.
4. Turn the battery switch off.
5. Close the fuel tank cock.
6. 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.
CAUTION! If seawater is left inside of
the engine, it may freeze and damage
parts of the cooling system when the
ambient temperature is below 0C
(32F).
Electric Emergency Stop:
CAUTION! NEVER use the Emergency
Stop switch for a normal engine
shutdown. Use this switch only when
stopping the engine suddenly in an
emergency.

Figure 6
Push the upper part of the Emergency Stop
switch (Figure 6, (1)) on the right of the
panel and the engine shuts down
immediately, without the time lag of regular
engine shutdown. After shutdown, push the
bottom part of the emergency stop switch
(Figure 6, (2)) to be returned to the former
position. NOTICE: Use this switch only in an
emergency. Under normal circumstances,
use the OFF, Eng ON, Start switch
(Figure 6, (3)) to stop the engine.
