I was interested to come across this discussion as I have had a similar problem. I am in my second season with the boat, a '97 MarkII, and this spring discovered water leaking into the aft bilge compartment from the plywood base under the galley sink cabinet when the system was pressurized, right at the forward corner over the bilge. I assumed there was a leak in the various hoses/connections under the sink, but could not find anything. Finally asked the yard to take a look at it, and they claim to have found a small leak in the hot water heater. So they disconnected the cold water intake and hot water intake and joined them together in a loop so there is no water going into the hot water tank. I am still testing and am not entirely convinced that is the leak (or the only leak), but we shall see. We may or may not replace the water heater this year.
Meanwhile, here is my newbie question, this being by my first hot water heater. Is there any problem leaving the coolant hoses as they are (trying to heat a tank with no water in it, a tank that will likely never be used again). Or do we have to doing something further at this point?
