"Does anybody here have a water heater that heats water from the engine coolant? (heat exchanger?)
If so, how is it plumbed? My boat had one on one of the old engines, but, I forget where/how it hooked up. I notice there is a pipe plug on the water pump, just above the coolant outlet to the heat exchanger, but don't know if this is one of the hookups. Thanks"
