6-71 rebuild

If it is the guy that rebuilt your old 6-71 ....He is worth it the egine hums!!!!!!!

That's the engine I rebuilt, Mike. But the guy I'm talking about lent me some tools and provided a few good info-nuggets as I was working on it.

Oh, and I had the skinny redneck helping me cuss and throw tools when I ran into tough spots.

[Tuna Taxi]

Yeah, I've still got the template. Give me a yell when you haul her and I'll drop it by.

I had my 2 410hp. 6-71's rebuilt 2 seasons ago for $16,900... By a old school Detroit man... 2337 hrs. later all I have had to do is change 1 injector @ 157 hrs.

This 3-4k a hole seems awfull high... I also know a guy who spent $17,000 for J&T to rebuild one engine....

I do agree the 485 hp. motors dont last long.

As I said it's a rule of thumb. It has a little to do with cylinder kits and a lot to do with all the extras. Pumps, intercooler, heat exchangers, turbo, blower, injectors etc. (BTW Tuna Taxi, good call on the Interstate injectors.) Remember, the turbo on the TIB is water cooled and will cost almost twice what the dry type does. Does the crank need to be ground? Is it being done in the boat or out? This is why I said to get an itemized list.

You can always find somebody who will do it cheaper and it will run, but for an engine that's already pushed to the max the question is for how long. Mechanically Detroits may be simple, but the devil is in the details. Fitting liners correctly on a 71-series takes a lot of careful measurement which is labor intensive. It's not a wet-liner engine and if the liners are not fitted correctly they will not transfer heat efficiently and will fail sooner. All I'm saying is a good and complete rebuild of this engine that will get maximum life (such as it is) can not be done on the cheap.

One other thing that's really bugging me, unless your mechanic is working out of his garage and putting in kits only he is not putting $12,000 in his pocket. To imply that he is is unfair to say the least and does a great disservice to professional mechanics. I suppose charter captains are pocketing a ton of money over the fuel cost too since they don't have to pay their mates and they have no other expenses right?

Does anyone have the Tel. # for Frank Butt (mechanic in Baltimore, MD)? If so, please PM me.
Thanks.
