I think that Kuuma are the closest as a direct replacement, but they don't last too long. Depending on how you use your boat, you may want to consider a water heater with a stainless tank. I installed an ISO-Temp heater (they are now part of the Webasto group). They come with the temperature regulating valve and they are supposed to be quite reliable. But the cost is usually a bit higher.

While working on my packing nut I noticed that one of the hot water leads from the heat exchanger snapped off. The inlet fitting was completely corroded through. Same with the other exit side. Glad I am still on land! It is a Force 10 and could even be original. Since they are welded on it is time to replace. I noticed that Force 10 no longer makes them and Kuuma is now the closest replacement? Looks identical. Anyone have one of these? Thanks. John McCrea Talisman 1979 36-1 Mystic, CT
