I put 20,000hrs (not a mis-print) on a Perkins 6-354, then rebuilt it. The new owner is now on his second great loop.

Parts are available in every country in the world at farm equipment outlets
(30%cheaper parts than"marine" outlets).

Transatlantic Diesel often have rebuilds for sale.

yep, If you can find one, one of the best ever made and about 85 HP. Lots of parts around due to it's wide use even in forklifts.

We're 54ft on deck and approx 30 tons. We have a 120hp 6 cyl. Ford Lehman which is an old but fabulously reliable work horse.
American Diesel was set up by Bob Smith, and he originally set up the whole Lehman production for Ford. His son, Brian now seems to run the show. Very knowledgeable and helpful.
Maybe give him a call and see if he has any suggestions. I don't know if they deal in reconditioned engines but a Lehman is good for 25,000 hours if looked after.

Vic, good to hear from you. Charlie Loader and I are still at it up here on the "Rock" Bermuda

Well, Trans Atlantic is "out of this model, we may have some more this fall". Grrrr time for a google search.
