    '86 merc 60 prop shaft has marks, fix?

    Replacing the seals on my propeller shaft. The shaft is worn in that area, has 3 or 4 barely visible scratches running lengthwise on the shaft. Also shows shiny where the seals contact the shaft. Can I sand it with 400 grit emery cloth and fix it, or is it done?
