Very simple and basic to implement and maintain

I dunno about your engine, but the westerbeke bolt-on components have a less than stellar rep. It is a basic system and you would think it would be reliable, but I've had to rebuild my jabsco saltwater pump 3X since I bought this crazy boat. And there have been several posts on the CSOA website with people having problems with the heat exchanger system.
I think it can be simpler, that's all. I just wonder if anyone has tried conducting the excess heat through the hull. Obviously a steel boat would be better to test this, but I don't think it's a requirement. When I get some time I would like to look at the numbers further.

I wonder if you had a steel hulled boat and then ran the hot water through copper coils that were fixed to the inside of the hull.....I suppose the problem would be how to keep the maximum amount of surface area of the coils fixed to the hull.

Very well said. All we need our OB for is getting in and out of the marina and that's because the marina is on a large river. Next year this time we will be on a 6 month cruise in the Bahamas and engine time should be about 3 hrs for the trip.

|RandyonR3||You know guys, I know I'm going to catch hell on this one, But..ITS A SAILBOAT..With a note on SAIL... If you dont like the way the motor works, put the sails up.....and if you find you're spending more time motoring and less time sailing, maybe its time to go over to the DARK SIDE.......|

I was just rambling... And I'm with you on the corrosive sea-water -- the heater exchanger should last decades with proper use -- not bad service considering. Perhaps I'm in the minority, but I've always felt it was an elegantly simple solution.
Hey, I'm glad TrueBlue mentioned it, becuase now it occurs to me that maybe we could direct the thrust from the SailFans to also blow air on the radiator? This could be even more revolutionary than any of us realized...

I totally agree, which is why my boat has a raw water pump and a heat exchanger I am not at all bothered by the fact that I am sucking up corrosive sea water and using that to cool the coolant in the engine.
The original post was concerned, so I just offered a tried and true method of cooling an engine. I don't think a air - water cooled radiator makes sense, but to each their own.

|TrueBlue||John, I will be awaiting the results of your SailFan experiments with voracious denial.|
