    Would the newer, stainless steel shafts from a later 7.5 Merc
    fit the older units like my dad’s 1973?
    Thanks.

    I believe that the newer shafts would work in the older motors. I do know that in the 20hp line, from 1963-81 that the new style stainless drive shafts will work for all years. There is a slight difference in the water pump drive, so you may need to update the water pump impeller and drive key with the shaft.
