8.14 EXHAUST SYSTEM
The engine exhaust system is equipped with a double chamber muffler
(one on each engine). These mufflers allow to generate a very low
counterpressure inside, so that the hazard of water flow-back to cylinders
is reduced, otherwise the propulsion system could get seriously
damaged.
The exhaust system is conceived so as to eject water and gas together.
This reduces remarkably the combustion noise and the noise produced
by the same engines.
Check the underwater exhaust terminal cleanliness conditions periodically.

WARNING
When starting the engines, check that the exhaust discharges water;
this means that the engines cooling system and exhaust cooling system
work correctly. Accelerate if no water comes out.
If the problem carries on, refer to the BERTRAM Customer Support.
