Water heater
Hot Water Outlet
Heated water from the engine’s cooling system can be
used to heat hot water tanks, cabin heaters and other
accessories on a boat.
The water is drawn from and returned to the engine
with a system of fittings and hoses. A typical system
for a seawater cooled engine is shown
If your engine is equipped with a hot water outlet sys-
tem the impact on normal boat operation should be
minimal. Keep the following in mind if your engine has
this system:
•
The extra hoses and the accessory add capacity to
the cooling system. It may take longer to heat up the
engine.
•
For freshwater cooled engines, the extra capacity
must be accounted for when replacing the coolant.
•
For seawater cooled engines, the system must be
drained during freezing conditions.
NOTICE!
Risk of severe engine damage, for seawater
cooled engines, if the hot water outlet system is not
drained during freezing conditions.
