Mfg specs suggest you don't install fresh water cooling on an engine with over 125 hrs or 1 year whichever comes first. I think you're over both.

Rust in the engine cooling system will flake off and plug the heat exchanger. On the side you can't clean out. Try it if you want, you will have about of a 50/50 chance of it working. All you loose is the cost of the heat exchanger,
