If you have an installation with
two or three engines, and only
one engine is operating, it is
important to limit the amount of
throttle applied to the running
engine. If you observe black
smoke or movement of the
0000086en
throttle does not increase engine
RPM, you are overloading the
engine that is running.
Immediately throttle back to
approximately 2/3 throttle or to a
setting where the engine
performs normally. Failure to do
so may cause the running engine
to overheat or cause excess
carbon buildup which may
shorten the engine's life.

If you have an installation with
two or three engines, and only
one engine is operating, please
note that if the propeller shaft
thru-hull (stuffing box) is
lubricated by engine water
pressure and the engines are
interconnected, care must be
taken that water from the
running engine does not enter
the exhaust of the non-running
engine(s). This water could
cause seizure of the non-running
engine(s). See your authorized
Yanmar marine dealer or
distributor for a complete
explanation of this condition.
