I am thinking about repowering my 76 36c from gas ( very old 454s) to diesel and I would just like to get an opinion on some price quotes I got from two yanmar dealers. I got a quote from a dealer in NY on LI for $70,000 for 315 yanmars w/trans and generator installed "barring any problems" with...

I know these engines have a history of leaking oil but I'm curious how much is normal. I seem to be losing about a gallon each for every 10 hours of run time. Engines have about 1300 hours on them. Much of the seepage is coming from around the dip stick with other minor losses at assorted...

I ahve VT-903M engines and TD 509 2:1 Gears 1975 42 C. I would like to talk to anyone with this configuration about HP ratings and CPL numbers . Mine were 400HP at 2600 RPM original. Previous owner had them set to 2800 RPM trying to get 425 hp--is this possible? Second, what are the corect prop...

I was wondering if anyone out there has a clue whether or not the 454's in my 1985 32FB would fit in place when I crane them in WITH the risers and elbows ect already on them? I took the engines out with the FWC system disassembled because I was nervous about it not coming out of the engine hatch...

I must make decision to repower vs overhaul current 1966 DD 653's. want cleaner, quieter, faster performance in my 41 TCMY. anyone with info on cost, complexity, and performance much appreciated.

Well, after all the looking for and finally finding a satisfactory 53MY and obtaining and paying for a slip that it will fit in we decided we are not going to buy a boat. I received quite a few private emails from folks on this site and I really appreciate them. They helped the Admiral and me...

I'm looking at a 1973 Hatteras MY,FB.Nothing special.Plain 6-71 DD.The boat has been out of the water for 2 1/2 years and not going back in this summer.It is a fresh water boat.I think it was put up by the Marina for the winter, short storage.I have not been inside the boat.The outside hull looks...

I have a 1979 43DC ... the rear fuel tank sending unit won't register beyond 1/2 tank ... so I'm assuming that the float has gone bad ... any suggestions on replacing the float? Thanks.

Over the weekend while swimming off the back of the boat I heard a snapping noise seem to be louder at the gen exhaust. I turned everything off but the generator and back on one at a time it would grow fainter but never completely stopped. Wondering if anyone has had same problem.

Started cutting out what is left of the deck coring. Seems no one properly sealed holes cut in decks for fuel fill fittings tower supports and haws pipes (factory install) or the rod holders (not sure who did these). The coring is completely gone.The good news is it is not that hard to access...
