INSTALLATION
2 "SUPER SILENT" EXHAUST SYSTEM
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 sepa-
rator allows the cooling water to be ejected through a
line (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 600 mm above the water level an
additional goose neck is not required.

If the through-hull exhaust outlet has to be mounted
far (total length exhaust piping from generator to top
of goose neck (waterseparator) is more than 3 m)
from the generating set, an exhaust/water separator
must definitely be installed. The sea water from the

separator must then run down along the shortest pos-
sible path to the through-hull outlet. Only after the
exhaust/water separator the exhaust hose may have
alength of over 7,5 m if the exhaust hose diameter is
also increased from 40 mm to 50 mm in order to re-
duce the back pressure (ref. to fig. 9).
Hohwever watertraps should be avoided as the
fumes still contains water and this should not
accumulate in bents. (Refer to fig 8a) An additional
outlet exhaust muffler close to the hull outlet will help
further to reduce noise emission.
