"SUPER SILENT" EXHAUST SYSTEM
See figure 11. In order to reduce the noise level of the
generating set to a minimum, an option to reduce the
exhaust noise further (especially exhaust water splashing)
is an exhaust/water separator. The exhaust/water
separator allows the cooling water to be ejected through a
line (figure 11, ref. A) separate from the exhaust fumes
and also functions as a goose neck to prevent water from
flooding the engine. If the exhaust/water separator is
mounted more than 24” (60 cm) above the water level an
additional goose neck is not required.
If the through-hull exhaust outlet has to be mounted far
from the generating set an exhaust/water separator must
definitely be installed (Total length of the exhaust piping
from generator to top of goose neck (water separator) is
more than 10ft / 3 m.) (ref. to fig. 12).
The sea water from the separator must then run down
along the shortest possible path to the through-hull outlet.
Only after the exhaust/water separator the exhaust hose
may have a length of over 25 ft (7.5 m) (ref. to fig. 12)
However watertraps should be avoided as the fumes still
contains water and this should not accumulate in bents
(see figures 13a and 13b). An additional outlet exhaust
muffler close to the hull outlet will help further to reduce
noise emission
