The generator should have its own separate exhaust installed so that the entry of raw water
into the engine's exhaust manHold and cylinders is prevented while the engine is nOl running,
or while the vessel is under sail or power in which
case
the vessel may experience heeling,
rolling or pitching. Special atlention ~ be taken to make certain the exhaust system is
secure, tight and free of leaks.
The raw water supply through-hull sea cock fittings ~ be of the flush-hull type. High-speed
scoop types or weed less scoop types must not be used,
as
they tend to encourage siphoning
of raw water through the cooling system filling the exhaust.
When a water lift type exhaust system is used (figure 3.13.4), the exhaust muffler should be
mounted
as
close to the engine as practical. The exhaust 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.
