3.3 Raw water circuit
The engine heat exchange circuit is represented in the block diagram below:
The sequence is as follows:
1 the raw water cools the internal coolant circuit is cooled;
2 then the raw water passes a hose connection to the injection point
3 then the exhaust elbow is cooled
4 the the raw water is injected into the exhaust gasses and mixed with the exhaust gasses it goes overboard.
IMPORTANT
If the injection point at the exhaust bend of the engine is situated at a height less than
15 cm (6”) above the waterline an air vent must be installed; see ‘Exhaust system’.
