As regards the installation the engine compartment is insulated on partition bulkheads. The
engine is accessible if you remove the stairs of companionway. In addition you can open a
flap hatch in the shower room and in the rear cabin to get access to all the important
components of the engine. Oil dipstick is able to be controlled through maintenance hatch in
portside stern cabine.
4.1.1 Exhaust system
The yacht is equipped with a wet exhaust system, i.e. cooling seawater is injected into the
exhaust outlet pipe, which cools the exhaust fumes. This mixture is taken downwards to a
silencer/water collector – mounted under the double berth. The pipe continues on towards the
stern and forms a swan’s neck in front of the starboard inner edge of the transom.
The exhaust pipe is made of synthetic rubber reinforced with a steel spiral. The pipe is heat-
resistant, although with certain limits. Do
not
interrupt the sea water supply. Attention must
be paid therefore to provide a continuous supply. The pipe is fixed at all connection points
with two clamps.
