Does anyone have an idea of what it might cost to get a Detroit Diesel 471TA rebuilt. Just some sort of range to estimate the expense would be great. Thanks
Sounds about right. The boat next to me is having a 6-71 rebuilt right now for $20k. Have you looked to see if you can find a swing rebuilt engine? Sometimes you can find a deal.
If you or a friend can do the work, a 471 engine kit runs $900-1000 and the head will cost about $1000. The only critical part (different from gas engines) is shimming the sleeves to the proper height and setting the rack. I did my two 671 naturals for about $5000, including the heads.
The old sleeves should have numbers on them so you can get exactly the same again.
Its been a while but I paid about 3k for the head work, new sleeves with pistons loaded, new injectors and gasket kit. Labor I swapped out for building a shed. I just hit about 18 hours on the new engine and it runs great. Old mechanics are hard to find but love to barter. I've got to go build an addition on his house next for the other motor, when ever it gives up the ghost.
I am just interested because on engine has already been rebuilt. Both work well but I just wanted to know what I was getting into. I think the new one has about 900 hours on it. The port engine, who know. Looks well used. Buying the boat anyway because it is such a good price. I can afford to put 10K into it and still be OK. I should have a nice piece if I do. Thanks everyone.
