    engine swap for Tollycraft 48

    Good Morning all...One thing that I didn't mention in my original post is that the boat has been sitting on the hard for two and a half years untouched.In my experience with airplanes and boats low or no operation is the bad news.I hear that 671's can sit for years and start right up and run but...

    engine swap for Tollycraft 48

    Well....Since it is closing in on cocktail hour here in Port Salerno I think that I might get ready to pour one and mull over all of this information that I have learned today...Since one of the 671n's has 450 hours since rebuild and the other one 54 hours I think that I might back up my thought...

    engine swap for Tollycraft 48

    Thanks...Good information.All of it and it does have me thinking.I expected that I wasn't looking at a simple task ( $$$) but you mentioned lots of things that I didn't even think of. The salon is going to be done over and I knew the windows have to come out..By the way all of the windows and...

    engine swap for Tollycraft 48

    Thanks very much..Good insights on potential issues that I was not aware of.No experience with old diesels, just MAN's, Cummins QSM 11's and Volvo D12's on my last three boats.I'm in a new world here so I really appreciate all the advice I'm getting on the forum.

    engine swap for Tollycraft 48

    Thanks for the tip on soft cores above the sliders.I think that Bounty in Anacortes makes replacement doors and windows but knowing that there may be an issue to fix is very helpful. Probably would not use higher speeds that much except running from the storms in the Bahamas ( which I have had...

    Thanks for your response.300 Jo on the 671n's...Low hours on rebuilds but looking for quiet.If someone has any ideas about how to quiet them down ( insulation of course) I would love to hear.Like to cruise at 15 to 17kts.

    engine swap for Tollycraft 48

    Thanks...I hear you on value added issue.I know that engine noise will bother my wife a bunch and the seemingly sweating of oil through the pores of the 671's would annoy me but I appreciate your input.Thanks

    engine swap for Tollycraft 48

    As part of a restoration project I am considering a swap from Detroit 671n engines to something cleaner and quieter.The Cummins 5.9 series seems to be what most people suggest on misc sites and also Yanmars as an alternative. Cummins has what seems to be a good choice with remanufactured...
