Re: Raw Water Heat Exchanger teardown, Westerbeke
Thought I'd mention an idiocintxrisy of keel coolers over H EX . The water pump under the thermostat is not positive displacement and at a long slow idle may not be circulating enough down and around.. Temp alarm and an eye on gauges a good thing. That be good with air lock in a regular hx setup too. Last time I looked, most of the fishing boats had keel coolers.
