I have a 1975 70 HP Evinrude that I replaced the seals in the lower unit because I had lost all the oil. It still leaked. I took those out and put in two more. They leak. I looked at the prop shaft to see if I could see any pit marks. None. I even used a fine sandpaper to smooth it before I put the new seals on. Do you think that a bearing is shot and the shaft is wobbling? I checked for wobble and I couldn't detect any, but am not sure that how much it would take to make it leak.

you also need to use locktite to seal the outer ring of the seal.
