I am looking at buying a 36' boat equipped w/a pair of Marine Cummins V-555-M 230hp, 1972. They were zeroed out in the 1990's and now have about 900 hours on them and are apparently in exellent shape. My question is: are these engines worth putting any $$$ into to beef up the hp? I have been told that I could ad turbos and reach about 270 hp. Is this worth the $$$, as opposed to repowering w/ new Cummins or Cats at appx. $70K for 300 hp engines?

Any advise would be greatly appreciated.

These are OLD tech motors, and very heavy for their output. I'd be looking to change them out for B or C series motors, especially if you travel far offshore. Personally, I'd not put any money into trying to increase the output of any old motor. Adding stress/heat to it will hasten its demise, and bring out any weaknesses. If you're mechanically inclined, buy used motors and rebuild them. Its not as complicated as it seems, and the knowledge gained can save your a$$ in the future. Good luck!

NO, do not waste the money. Listen to what kapnD replied to you. You can get the same or more horsepower form a B or C Cummins at a lot less cost and confusion. The New electric engines are more compact and by far easier to maintain and, much more fuel effeicient. If you need the extra weight of the 555,simply add ballast somewhere. GO with a newer engine, especially if emissions may affect you in the near future.
