"I have a mercruiser 233 in the 24 ft fibreform to the left.Ford 351W. A plumber friend of mine has taken a commercial grade hot water radiator and adapted it to fit the 1 inch lines I have on my closed cooling system. He has intalled two valves, one that is on a bypass to open when heat is not required . If I want heat, I open the one that feeds through the heater and close the bypass.I realize that one MUST be open at all times for coolant to circulate. I plan on plumbing it into one of the two lines that run from the water pump to the riser. My questions are, will adding about 10 feet of hose make much difference in coolant circulation and are ther any other associated problems I should be aware of before going ahead and installing it. He tells me that 150-160 degree water should more than heat the boat."
