Oops sorry about that I mean the Stern tube we have to change the Stern tube large project. Just wondering if anybody else has done it?
Yes but 1975 mt34 has a false floor

We removed both shafts (twin diesels) and easily pryed our stern tubes off.
It had old stuffing boxes and during repacking realized after a better inspection that the stern tube needed rebeding. Just like every thru hull.
The mistake we made in rebeding port side with 5200 ( maybe a mistake on this side) is it wasnt completely straight with the shaft.
We converted to pss dripless shaft seals and the port side will now spray water do to be uncentered with shaft.
I suppose after time the carbon ring will work its self to proper seating but I don't want all that spray in the engine compartment.
Next project will be trying to remove the 5200 and rebed.
It could be an optical illusion but it looks like the stern tube is not axially aligned with the shaft and therefore the bellows are not concentric on each end. PSS seals do not like that. The graphite seal needs to float on the shaft and not rub on it. It looks like it may be rubbing which will cause spraying if there is any vibration. I've found I need to be very careful with the position of the bellows on the stern tube or it sprays. Once it's aligns if you spin the shaft you should be able to move the graphite seal all the way around towards the shaft and have some movement.
