interesting about the overheating. Did it just happened or was it there before. As I mentioned, I have the Volvo TMD22P with 4900 hours. The temperature gage was showing 195*F or 95*C. It felt a little warm to me, I would have prefer seeing 10 degree less. But even after motoring for 14 hours would remain the same (which was a good sign). The hour meter (changed in 2012) also was working on and off, and sometime the tachometer was going all the way. When I went to Fort Lauderdale last year, I explained my concern to Diesel of America. In short (different story), I was taken advantage off, $9000 later, I am running hotter… I am skipping the lie and non-sense replies (will be happy to go in detail on another post), after “5 months”, it was finally back to what it was. At the end, an answer I don’t totally believe. I was told that theses engine run so cold that they made sensors and gages showing a higher temperature. (I had the gage checked and it shows the right resistance) I had added a second temperature gage and it does show 20 degree less. May be this will solve your overheating problem. But if it just happened, then a new engine is in order. But with $9000 of expenses (not including spare alternator, injector, fuel pump, hoses, etc.) I thought I should have replace it since was probably half way to a new engine. Not sure about the labor cost. The decision is yours, a balance between piece of mind, cost, etc. Just be very careful about the grounding as the other mentioned. Based on Kent experience, this could cost you much much more time and money… Hanspeter, thanks for the temperature informations! Viet thanks for the info, I remembered you didn’t had the gage.

Subject: Re: [Amel Yacht Owners] Repower To: "amelyachtowners@..." <amelyachtowners@...> Date: Thursday, June 25, 2015, 10:01 PM Since I seem to have started this repower thread, I'll tell you why we have decided to repower. As with any decision, I have multiple reasons that have influenced our choice. Our Perkins Prima has 4200+ hours, and has had various issues in the year and a half we have owned the boat. Currently we have a overheating problem that we cant seem to completely cure. If I keep throwing money at it, we will probably eventually figure it out, but who knows. The wiring harness for the entire engine is old and brittle, and really needs to be replaced. The engine panel warnings are not working, the tach just went out, and a new panel is quite expensive. To rebuild the engine, fix all the other bits and pieces, is going to cost about 3/4 of the price of a new Yanmar. Part of the problem in the USA is the cost of parts and labor doing a rebuild. We are about embark on a 10 year circumnavigation, and the thought of a reliable new engine with a warranty for 25% more $$$ than rebuilding an old one seems like a good deal to me. I also suspect when we sell the boat after our circumnavigation, we will get a much better price with a mid time Yanmar vs a 32 year old Perkins with 7000 hours. I guess only time will tell if we are making the right choice, but I'm comfortable with it. Also, we should be back on the water in 2 or 3 weeks, but with a rebuild, we would probably loose most of the summer. In our case, we have spent the last year re-fitting the boat, are ready to go, and it is worth a few $$$ to not lose our summer of sailing.

I can still reach the hull speed of over 8 knots and I can still power into a 30 knot + head wind and still make way comfortably. The engine has proved to be very reliable and economical to run. If you put two identical Amel's side by side, one with a Perkins/Volva 80hp and one with a Yamnah 110hp and ran them flat out, I doubt if you would see any difference except a larger hole in your pocket. It is my opinion one would be better of spending the money and giving your existing engine a full overhaul. The Perkins is a very good engine and if the maintenance is kept up, like any engine, it will provide many hours of service. I know I can get parts anywhere in the world so why bother? Just my two bob's worth.
