The generator should have its own separate exhaust installed so that the entry of raw water into the engine's
exhaust manifold and cylinders is prevented while the engine is not running, or while the vessel is under
sail
or power in which case the vessel may experience heeling, backing down from following seas, or any other
conditions. Special attention lI1..U.S1: be taken to make certain the exhaust system is secure, tight and free of
leaks.

be
of
the flush-hull type. High-speed scoop types
or weedless scoop
types
must
not
be used, as they tend to encourage siphoning.
When a water lift type exhaust system is
used, the exhaust muffler should be mounted
as close to the engine as practical. The ex-
haust discharge should always drop
downward into the exhaust muffler. Loops in
the exhaust hose between the water-injected
exhaust elbow and the water lift muffler
should be avoided, as these will trap and hold
water.
For installations where the exhaust
manifold/water-injected exhaust elbow is
close to or below the vessel's water line,

vent, when used, l11.U.Sl have its vent hose or
tube routed so it can remain above the water

shut down. This allows air
