Graham, Thanks. I got a water heater with stainless steel heating tubes for that very reason and frankly if the water heater last 3 or 4 seasons that will be fine. Is yours plumbed that way?

Your hot water tank might not last too long.

I realize that the raw water cooled engine runs cooler than then one with a heat exchanger but I can live with warm and not hot water. However, I was told by a mechanic that this could harm the water pump but since it's simply a rubber impeller turning on a shaft I don't see happening. He also suggested that the increased length/back pressure will lesson the flow through the system. So, I'm curious to see if hooking the water heater to the 3GM cooling system will harm the engine.
