No noticeable leakage at rest. 2005 Tiara 32 open. access looks like a bear. Anyone do this themselves?

Twin Volvo 310 diesels if it makes a difference!
Make sure it is the dripless shaft before taking it on. I thought ours was leaking, but noticed water coming in through the transducer for the depth sounder. It was not noticeable because the infloor fish box concealed it. I noticed the leak when doing some cleaning. Fixed that and the bilge remained dry. Replacing seals requires pulling the boat. There is sometimes a spare seal that is installed and can be used. If not, the prop shafts need to be disconnected from the transmissions before installing the new parts. After that, realign the flanges and you are good to go. As you point out, space is not good.
