Operator`s manual
Location
The location should be such that it
is
dry, above low-lying vapor areas, and away from being splashed
by
bile water or water from above.
It
should be properly ventilated and accessible for minor servicing and
repairs. Access for major repairs should
be
given consideration as well. The location must be properly
ventilated to provide the fresh cooling air for the generator end and for engine combustion. Hot generator
discharge air must be removed from the generator area. The platform on which the generator and its
mounting rails are located should be strong enough to support the generator unit during all angles
of
vessel operation.
Exhaust System
The exhaust system provides an outlet line
to
vent engine exhaust gases out
of
and away from the vessel.
The system also discharges sea water which has passed through the engine's sea water circuit by mixing it
with hot exhaust gases. This mixing helps to cool the exhaust gases and exhaust elbows and pipe. The
exhaust system and the sea water supply
to
the exhaust must be configured to prevent the siphoning
of
sea
water into the exhaust through the sea water cooling circuit and to prevent the entry
of
sea water into the
exhaust through the circuit's thm-hull discharge port.
If
not prevented, sea water entering through the
discharge port can fill the exhaust system's muffler and enter the
engine's
cylinders. This will prevent
proper starting and possibly cause damage
to
internal engine components.

Exhaust
The sea water supply hose to the exhaust system's water injection elbow should be routed (looped) at least
12
inches above the vessel's water line. An anti-siphon break should be installed at the top
of
this loop
when the generator set is installed at or below the water line. The top
of
the loop should be placed high
enough above the vessel's water line
so
as
to
remain above the water line when the vessel is underway, no
matter what the angle
of
heel or roll may be.
The sea water supply thm-hull seacock fittings must be
of
the flush-hull type. High-speed scoop type
fittings should not be used, as they tend
to
encourage siphoning.
