6.2 Water-Cooled Exhaust
Manifold
Each marine generator set has a water-cooled exhaust
manifold. The coolant solution circulates through the
manifold, reducing the amount of heat radiated from the
exhaust into the surrounding area.
The engine thermostat is located at the location shown
in Figure 6-2. Always replace the thermostat gasket
every time it is disassembled.
