I want to install a closed cooling system in my boat, an aluminum duck boat powered by an inboard jet motor 455 olds(yet to be installed). I want the closed system so I don't have to worry about freezing as I want to use it for a duck hunting boat. The problem is that in Kansas there aren't many closed systems around, and I do not know how they work. I think I could even use a radiator since I have the space. Has anyone ever built anything like this?
