Been away for a while, Im back looking for engine advice.
I have a 50 ft steel Roberts. Plans call for 40-80 hp. I'm partial to perkins,non turbo. I'm thinking 4 cylinder, but looking for advice. I need the entire powertrain. Any tips or advice is welcome.

I'd be much happier at the 80hp end of the range.
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.

Re: Been away for a while, Im back looking for engine advice.
I put a John Deere 4045D (85hp) into Boracay (Roberts 44 offshore, about 15 tonne) and have experienced no problems at all. I also put in a ZF63 which has performed well (Did need a copper washer changed).
Given all the problems involved in a repower why not go for a larger engine, either a reconditioned Ford Lehman or a new John Deere 4045T or even a John Deere 6068? The difference in cost is likely to be small.
Do check that the propeller shaft can handle the extra power.
I found the bigger engine gave great peace of mind, particularly to my senior crew.

Re: Been away for a while, Im back looking for engine advice.
Thanks for the input, She has a 44mm prop shaft. I'm looking at a perkins 4.236 with transmission on the Trans Atlantic Diesel web site. Still waiting on a quote. Are there any dealers here on this forum that sells this engine?

Re: Been away for a while, Im back looking for engine advice.
I know you said Perkins but if I ever repower I will go with Beta Marine. Excellent engines, great support, parts are reasonable many available from Kuboat tractor dealers.
Everyone I have ever spoken with that went with a Beta has been completely happy with the choice.

Re: Been away for a while, Im back looking for engine advice.
My concern is finding parts in some remote corner of the world. I may never get there but I plan to spend a lot of time away from here.

Metal Man Matt!!! Welcome back!!!!!!!!!!!!
Weather been nice to ya? (don't answer that)
I say Skippy has a good idea there... The Kubota is all over the world... As you can see by it even being embraced here in the South.... Parts are reportedly not an issue.... Go big man... 50hp not enough methinks...
PS: you need to make me an anchor....
