      When I was taking the guts of of subject motor LU gear box,
      a little steel, stepped bushing fell out. I was told that it
      was a locating pin for the prop shaft thrust bushing. For
      the life of me, I can figure out where it goes. There’s
      a hole in the side of the bushing and a matching hole
      in the bushing bore (on the bottom side), but the hole
      is too big for this little locating pin / bushing.

      Anyone recognize this locating pin and know exactly
      where it goes? Am I missing any parts?

      UPDATE 6-26-2016 – I woke up smarter today and
      got the locating pin figured out.
      Install the prop shaft thrust bushing (sliding fit) into
      the housing bore, install shouldered locating pin / bushing
      into the thrust bushing from the inside of bushing.
      Installing the prop shaft keeps the locating pin from
      falling out.
      Sill curious what any manual would say about the
      drive shaft seal, (see below) which brings up
      the point, are there any manuals that cover the
      early Chris Craft outboards?

      Also, the fuzzy parts diagram shows a drive shaft seal.
      I was told not to mess with it. Sounds like good advice,
      but am still curious to know how it was replaced?
      I’m guessing it would have to be pulled out along with
      the drive shaft bushing with a long threaded rod.
      Is it an actual seal down that long hole, o-ring, or ???

      Your wisdom appreciated!
