Engine Cooling System; Exhaust Gas System; Ventilation/Airing - Bavaria Cruiser 33 Owner's Manual

Sailing yacht "Bavaria Cruiser 33"

2.9 Engine cooling system

Engine cooling
The engine has got a two-circuit cooling system. Water enters through the saildrive, is led to the heat
exchanger and then injected into the exhaust gas pipe. Together with the exhaust gas the cooling sea water is
exhausted via the silencer and the exhaust pipe at the stern. This guarantees a trouble-free engine operation.
Moreover the engine noise is reduced.
All hose connections of the system a secured with double stainless steal clips.
Attention

2.10 Exhaust gas system

The yacht is fitted with a "wet" exhaust gas system, i.e. cooling sea water is injected into the exhaust gas
elbow causing a cooling of exhaust gases. This mixture is led down into a silencer/water lock, runs through a
pipe in the locker seat on the starboard side of the aft cabin, is led upwards at the stern and escapes to the
side above the water-line.
The exhaust gas hose consists of a synthetic rubber material with an integrated steal spiral.
The hose is heat-resistant (for some time) and should be checked and replaced if necessary.
A constant flow of sea water has to be guaranteed. The hose is secured at its joints with two clips.
If there is an interruption of the sea water flow, the temperature sensor in the exhaust gas hose will release an
optical and acoustic warning. In this event you should stop and switch off the engine immediately until the
problem has been settled (see manual of the engine manufacturer).
Attention
A regular Inspection if seawater comes out of the exhaust is urgently advisable.

2.11 Ventilation/Airing

We have taken the following measures for a proper ventilation of all rooms:
Chain locker
Certain ventilation is realised through its bilge holes at the bottom.
Living cabins / Salon
1 deck ventilator, 1 side windows and 1 deck hatch
Bow
Total 1 deck hatch
Aft cabin
1 side light, 1 side light showing to the cockpit, 1 folding hatch
Toiletroom
1 side window to the outside,
Components
1 side light, 2 deck hatches, 4 side light
Check and clean the sea water filter in regular intervals, depending on the
water quality.
Before starting the engine, make sure that the cooling water inlet is open.
Have a short look into the engine room for possible leakage.
When the engine is running it is highly recommendable to check regularly if
cooling water is escaping with the exhaust gas.
If the sea-cooling water cycle precipitates, the optical and acoustic warning
responds. Turn in this case engine off immediately and check the cooling
system.
