In some cases it may be difficult to raise the exhaust pipe as suggested; in that case proceed as
described in Figure 4. A. In case the cooling of the exhaust pipe is necessary, it can be arranged
by leading a small portion of the cooling water through a control cock into the exhaust pipe (Fig.
4. C). In this case, most of the cooling water is led directly from the cylinder out through the boat
side. A disadvantage of this application is that you have to remember to open the cock before use
and to close it after use in case the engine is located below or at water level. The exhaust pipe is
to be installed so that water entering the exhaust pipe or forming through condensation does not
enter the engine.
