Hi Dave
I heat water with a separate Espar heater, used for hot water and for cabin heat.

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?

Hi Dave
It should work, but another down side is that the salt water will corrode the heat exchanger coils - they aren't designed for salt water. Your hot water tank might not last too long.

    Does anyone on the list have a raw water cooled Yanmar 3GM hooked
    up to a water heater?

    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.
