I'll try and keep short
We had our 1330's re build this year, as they had some hours on them, worked great no slipping or any other issues in "pre rebuild form".

we had a local shop re build them, they installed new seal,o-rings, gaskets, clutch plates and steel plates, along with new out put shafts, we now have less than 3 hours on these tranny's, last week we lost one idling out to the lake, broke lose as soon as I inched the throttle's forward, trans was very hot to the touch...

WE Took it in And The Shop could not find any thing that could have caused the plates to warped ( @ that time I told them the other tranny is slipping, they blew me off).....$600 bucks later
( after paying $ 2500 each the first time) reInstalled and it runs fine for now.... Called the builder and I said that the other trans is slipping At plane off And As I roll on the throttles to accelerate. (I had origanally thought I was Cavitating So We instaled a 3/8" spacer but problem still persisted) I was was sure After the fore mentioned that the trans was indeed slipping & not prop Cavitation.. "He tells me it is imposible as once the clutches are locked they can not slip unless you lose pressure to the piston"....And yet One week later less a day the other Trans is smoked!!!
is there Anything he could have changed From the huber specs too cause this....??

The Shop is not standing behind their work... And it is quite clear in my mind they Are doing something very wrong, I have not changed the power infront of these tranny's and the builder told me straight up they will hold 1000 hp no problem, yet @ >900HP I can't keep them together after the rebuilds...
we Had no issues before the rebuild!

Any one have any ideas? please

Send it back to Huber, he was bought out. The new owner, has made changes on the trans for the better. I wouldn't allow anyone else in that trans. That why, it isn't working for you. Do you have the new address? I do but, at work.

BAM (long time OSO supporter) is a marine transmission expert. I would go to BAM before going to the new owner at "Huber". I believe BAM also has a transmission dyno. The dyno might be the tool you need to diagnose you problem. Trial and error is expensive.

Hmmmm.....Might want to read this: http://www.offshoreonly.com/forums/g...ease-read.html

Make sure you're using type F trans fluid.

Ditto BIG Daddy , Earl will make em right again might not get em back in a week but you wont go thru the crap your dealing with now ....

One reason: Huber,used to make them for Merc. Earl,also has a trans dyno.

Took the 2nd tranny in too the local shop, All the clutches & plates were warped to $hit, He called around And found that the plates were the wrong type for my 1330's put kevlar pates in dropped the clearance too .012 and Told me to beat the #ell out of it... And I did just that... Trans is almost 100 Deg cooler @ 6200 rpm And I can roll on the throttles hard with no slipping.... I'm about never burning a bridge...
I simply said "Dan I did not have these failures before... We need too find the problem" and I drove away... 6 hours later he called and said Come Get it It is done.... the inside was perfect, cluches were $hit... Now lets see if he fixes the other one....I guess It's hard to argu with two trashed trannys in one week....

P.S. $1300 of the bill was the planatary gear/ output shafts for each tranny...

Thanks guys for all your help... it it dose fail again it's going to either
Bam or Huber....Trial and error is Very $$$

Where did he get the kevlar clutches? Who is building them?
