1.5.3 

Exhaust system  

Water is injected in the exhaust system of the generating 

set. In this way the cooling water that has passed the heat 

exchanger is mixed with the exhaust gases. Temperature 

and volume of the gases are thereby reduced 

considerably, so that a rubber exhaust hose can be used 

and the level of noise is reduced as well.  

 

STANDARD EXHAUST SYSTEM INSTALLATION  

 

The generating set exhaust system must remain 

completely independent and separate from the exhaust 

system of any other engine on board. A water lock 

prevents the generating set from being flooded by cooling 

water and should be installed as close to the generating 

set as possible. The lock must be large enough to hold the 

entire water volume held in the hose from the top of the 

goose neck to the water lock. The water lock must be 

installed at the lowest point of the exhaust system (ref. to 

fig. 10, ref. 1). The exhaust hose must have an inner 

diameter of 2½” (63 mm). The exhaust system must be 

installed so that the back pressure inside the exhaust does 

not exceed 0.07 bar (1psi – 70 cm watercolumn) and total 

length from the genearot to the top of the goose neck or or 

water/separator does not exceed 10 ft. (3m). (Refer to 

paragraph 5.4.3 of the users manual).  

 

The exhaust hose descends from the capsule to the water 

lock. Then the hose rises via the "goose neck" to the 

through-hull exhaust outlet, situated minimum 2 inch (50 

mm) above the water line (see fig. 10, ref 5.) The "goose 

neck" must be vertical and situated preferable along the 

ship’s keel center line. If the generating set is mounted 

less than 24" (60 cm) above the waterline, a "goose neck" 

must be installed to prevent the engine from overflowing. It 

is recommended to install an extra muffler close to the 

through-hull fitting.
