TP-5695 12/93 6-10 Installation
Locate the exhaust outlet at least 4 in. (10 cm) above the
waterline when the craft is loaded to maximum capacity.
Usually a flapper is installed at exhaust (transom) outlet
to prevent water backup in following seas or when going
astern (backward).
WARNING
Carbon monoxide.
Can cause severe nausea, fainting, or death.
The exhaust system must be leakproof and
routinely inspected.
Carbon monoxide can cause severe nausea,
fainting, or death. Use the following precautions when
installing and operating generator set. Carbon
monoxide is particularly threatening in that it is an
odorless, colorless, tasteless, nonirritating gas. Be
especially careful if operating the generator when
moored or anchored under calm conditions as gases
may accumulate. If operating the set dockside, moor
your craft so that the exhaust discharges on the lee side
(the side sheltered from the wind), and always be
mindful of others— make sure your exhaust is directed
away from other boats and occupied buildings. Do not
install exhaust outlet where exhaust can be drawn
through portholes, vents, or air conditioners. If
generator set’s exhaust discharge hole is near to your
craft’s waterline, DO NOT OVERLOAD CRAFT so as to
close or restrict exhaust discharge hole.

Figure 6-17. Typical Above Waterline Installation
Exhaust system guidelines for various generator set
locations follow. Where exhaust lines would require
passage through bulkheads, it may be more practical to
use port (left) or starboard (right) side exhaust outlets.
This would be especially true where long exhaust lines
to the transom (rear) could cause excessive back pressure. Information and illustrations of stern (rear)
exhaust installations also apply to side exhaust
installations. Should any information regarding
installation
conflict with U.S.C.G. Regulations,
appropriate Regulations should be followed.
