Drive shaft question ProMax 2.5

**iwannagofast** · 09-01-2015, 11:07 AM

I have a lower with casting # 1686-827214C. it has 44104A7 gear set which I am replacing. The drive shaft seal area is very worn and corroded and needs to be either replaced or repaired. My question is has anyone had any experience with having these seal surfaces repaired. I can have it done fairly cheaply by my friend who has been a machinist for 40+ years and is excellent at his trade. The other option is to replace the shaft, but if I'm looking at the right parts breakdown the shaft is about $1100.00 retail. Can someone tell me the difference between this shaft(848449A4)and the 897624T shaft, used on most 2.5's? Also Maybe I'm looking up the wrong lower unit, so please correct me if so.

have it repaired!!! ive fixed plenty of them but with speedy sleeves , ive also added a fishing motor shaft to the torqmaster cases in lieu of the hard plated shaft they last a long long time they are stainless sorta buy a used one for a lot less just as good

A stock shaft will be just fine.
I personally do not like the speedy sleeve fix! If is not done correctly or by someone that has done them before it will not work properly, but that is just me!

Thanks for the replies. I have used speedy sleeves for other applications, but I expect difficulties with the distance from the end of the shaft to the seal area. What kind of tool did you use to get the sleeve all the way down the shaft without destroying the sleeve? This seems easier than what I had in mind which was to have it welded and turned down.
