It is quite hard on diesels to limit their RPM with a high pitch prop. If the tach is accurate, you might want to try a few inches less pitch.

If not, could be a bad tach.

Why go to the 3JH5? Mine seems satisfactory with the 27HP. My problem however is it doesn't want to develop more than 2800 RPM. Have a Martec 17x10 folding prop. Any suggestions. I have owned the boat since new and it's always been that way. What props do others have on their 41s ________________________________ Date: Sun, 4 Aug 2013 20:21:47 -0400 From: rsh...@optonline.net<mailto:rsh...@optonline.net> To: cnc-list@cnc-list.com<mailto:cnc-list@cnc-list.com> Subject: Re: Stus-List C&C 41 re-engine Paul, I have a 1984 C&C 41. No, I have not done an engine swap but I would be real interested in the details of the project. Seems that getting the old engine out would be the main concern. Relocating engine mounts should not be a problem. Of course putting the new engine in would be interesting. I am not contemplating an engine swap but I have played "what if" and thought that cutting the cockpit floor out and lifting the engine straight up would solve engine removal issues. With the engine out you would have unrestricted access for fiberglassing, painting, soundproofing and anything else you want to do down there. Good luck, Ray Shibe Stinky Dog.
