Re: Diesel powered sport boats?
 

They got the duramax with 3speed trannies running, but the trannie wouldn't shift.:mad:
The boat ran 100 in first gear with good acceleration, but that was all they could do for now. The owner wanted a comfortable 100 mph cruz. So if they get the trannie issues worked out he should be there. I'll let you know if I find out anything else.

Re: Diesel powered sport boats?
 

what kind of trannies ? Is this the old tommy bahama boat ?

Re: Diesel powered sport boats?
 

ttt diesel discussion... cummins 6B 5.9T this motot is used a lot in the marine world and produces a lot of power in trucks.. I'm looking for a head or a long block to start mocking up a tubular water cooled exhaust. I have some pics of tubulars instead of cast exhaust on trucks..
any sources on the board with a cracked heads or something just for mockups

Weisman, Yes it is the Tommy Bahama boat.

Build them and they will come. I'll take 3 in my next Nortech, I need around 450-500 hp and 750-800 tq. Can you have them by end of the season.:D Jeff

any more on this, or is their a web site that can viewed, thanks Jeff

Nothing apparently but the 6.5 surely aint the answer for larger boats But I´m sure a 6.6 will be.
I guy around here had twin penisular 300s on his Baja 420ES and nothing but problems with them 6.5 POS like almost everone on the roads up here too.
Couldn´t take the strain a heavy boat gives apparently.

Gale Banks takes 650hp and 1000lbs.ft out of them heavily modified but thenagain a Cummins 5.9 is also a top contender.

I'm working on the cummins 5.9 with a 2 speed powerglide behind it. I just wish I could get more info. I went to the diesel nationals, bet most people are secretive and think they have spent a fortune on their powerplants. One of the guys had 15k in his motor and thought that was A LOT... my dad and I think that a tame version of what he was running would be perfect in a boat.

I think I might just buy an old dodge truck and start from there, beacuse some of the 5.9 blocks that are out of china are junk.... and those are the cheap ones. a 12Valve without all the computer crap is probably the best in a boat and a lot less headaches getting it to run
