5.6 Installation of the water cooled exhaust system
5.6.1 Installation of the standard exhaust system
The generator exhaust system must remain completely independent and separate from the exhaust system of any
other unit(s) on board. The exhaust hose has an inner diameter of 30 mm. The water lock must be installed at the
lowest point of the exhaust system. An optional noise insulated water lock can also be installed. The exhaust hose
descends from the capsule to the water lock. Then the hose rises via the "goose neck" to the silencer (see drawing).
The goose neck must be vertical and sit preferably along the ship's keel centre line. In order that the back pressure
inside the exhaust is not to high, the total length of the exhaust system should not exceed 6 m (20 ft.)
By injecting the outlet raw water into the exhaust manifold, the exhaust gases are cooled and the noise emissions
from the exhaust system are reduced.

Installation of the water collector
Unfortunately, it can occasionally occur that, because of an disadvantageous mounting position of the water collec-
tor, sea water gets into the diesel engines’ combustion chamber. This disables the diesel engine by irreversible
damages. Quite frequently, this leads to discussions during which the parties involved in the yachts’ construction or
the installation of the generator have to explain themselves.
One point in this situation can be clarified definitely:
If sea water gets into the inner section of the engine, this is not possible due to constructional defects of the genera-
tor or to malfunctions on the engine itself. It can only reach the combustion chamber via the exhaust duct and thus
