I currently run my Palmer P-60 with no thermostat, basically due to not having a proper set up to install one, and comments from some people that the thermostat is not needed, and that the engine runs better when cool. My questions are..
1. Will the thermostat help with some of the blow by that comes from needing a ring job (that I am trying to delay), by causing the engine to run warmer, and "tighter?"
2. Will the higher temp allow for better combustion? My plugs are showing a lot of carbon, and I can't adjust the carb any leaner.
3. How do I find a tehrmostat? And is there a specific arrangement for installation
4. What is a good operating temperature for the Palmer P-60?
As usual, thanks to all of you for your responses.
I feel really good that its been over a year since I had to ask a question on my Palmer.

Well JB is the best to comment on most of your questions. I want to know are you running in salt or fresh water? If running in fresh I would suggest that 165F is about the hotest I would want in a closed cabin as the engine gets hot and makes it too hot to stay down below except in cold weather. If salt water not more the 143F as salt will percipitatate out of the cooling water and make a solid build up of salt in the water jackets and then you get terrible overheating problems to say the least. While I can supply you a thermostat housing for the P-60 until you do something about the blow by you are going to get carbon all over the plugs from burning oil not gasoline. If the engine is a salt water engine don't waste you money rebuilding the engine. Save all the marine trim. Have a tractor rebuilder take your marine crankshaft and rebuild a used IHC Lo-Boy C-60 engine then bolt all the marine trim on the engine and you are back in business. If your exhaust manifold is questionable junk the whole business and put in a small diesel is my advice.

If the motor's worn, I don't think a thermostat is going to make a big difference in blowby. It will help with combustion efficiency. Hotter motors run cleaner, last longer. Raw fuel in a cold motor washes lube from cylinders and dilutes crankcase oil. Moisture condenses in cold oil, heat boils it out. You're limited in a boat as Dick says, salt and cabin heat.
