I am going to re-power my 14x58 Sumerset that has one mercruser engine. Instead of using raw water I was going to use a heat exchanger. When I was talking about this one of our maintenance men spoke up and said use a radiator instead. I got to thinking and seems I remember a houseboat with a radiator mounted beside the engine. I looked online but either did not use the right keywords or this is not done?
Can anyone enlighten me?
