Speaking of hot water hoses and water heaters, has anyone heard of
engine overheat problems from running engine coolant (fresh water
system), a few feet (mayber 30 inches) above the engine block? I want
to add a heater at the helm, but my buddy, who did the same to his
similar boat, says the installer insisted on adding a circulation
pump. Not because there wouldn't be enough heat, but because "the
engine would overheat". This dosen't make sense to me since the
coolant flow for the heater is parallel to the engine cooling flow.
Even if the flow through the heater stops completely the engine should
still be properly cooled. Any experience or ideas?
