Westerbeke W-13 User Manual

4. Fresh water cooling system (See Note 5 on page 6.)
The system consists of a sea water pump which pumps raw sea water
through a heat exchanger to remove heat from the coolant. The raw
water is discharged overboard through the exhaust line.
The engine coolant (fresh water with or without antifreeze) is
circulated by the fresh water pump in continuous circuit. Pumped
through the cylinder block, cylinder head, heat exchanger and back
to the fresh water pump.
The total system is very reliable and requires only a daily check
of the water level in the system plus routine check of hose clamps
and fittings.
It is likely that zinc electrodes will waste away from contact
wi th sea water. It is also possible for the raw water pump
impeller to fail due to lack of sea water or deterioration. An
early sign of impeller failure is less water and more steam at the
exhaust through hull fitting.
I t is recommended, therefore, that zinc electrodes, an impeller
kit, a pump belt and a thermostat with gasket be kept onboard at
all times. These parts should be ordered from your nearest
stocking dealer and used as inspection dictates.
