KMH4A Marine Gear Only
In case of emergency, follow the following
procedure for using the clutch emergency
bolt to return to port.
• Using the emergency bolt directly
connects the clutch to the engine
making it possible to turn the
propeller. However, when the engine
is started and the propeller turns, the
boat will only move forward. The
neutral and reverse positions cannot
be used.
The emergency bolt should only be
used in cases where it is impossible
to operate the clutch and the boat
must return to port. Ask your Yanmar
dealer for repairs immediately after
returning to port.
• When using the emergency bolt, never
use the clutch as this will break it.
• Operate at low speed,
1000rpm or less, and
navigate carefully.
When approaching the pier
turn off the engine early and stop the
boat.
Perform the following steps after turning
off the engine:
1. Remove the hexagonal red bolts at the
back of the clutch with a spanner.
