        I removed the seal about an hour ago. Didn’t have a fancy OMC puller,
        and my futile attempts of prying it out were getting me nowhere.
        I could not drill a hole in the seal as my drill was too “fat” to
        get the right angle. Therefore, I spent about 15 minutes and pulled
        the front of the crankcase off.
        After seeing the seal area on the crankshaft, I see why the seal
        was blowing air on my test. It’s all pitted beyond hope.
        Not sure if there’s a “speedy seal” cure for this, but I doubt it.
        The pitted area can’t be ground out as the point lobe above the seal area on the
        crankshaft is almost the same diameter.
        Also, with the seal out, I got a proper measurement on the shaft size
        in the seal area.
        I measure 1.197 shaft. Specs online for the 308500 seal say
        shaft size 1.110 which is a little confusing to say the least.

        I will ponder my situation and listen to any suggestions, but I’m
        not looking to throw a bunch of money into this motor that I
        really didn’t want anyway, lol.

          There was no Speedi Sleeve option for this crankshaft. I attempted to contact
          a person on EBay twice regarding his $45 crankshaft, if the seal area was
          “okay” or pitted like mine. No Reply.
          Therefore, just so I could at least hear this motor run a time or two, I made
          my own “not so speedy” sleeve on the lathe. It’s made out of brass
          and about .027 inch thick. I ordered two, non original seals to fit this
          sleeve. The seals OD were smaller than needed, therefore I had to make
          another sleeve for the seal OD, about the same thickness as the shaft sleeve.
          This sleeve I made out of some PVC pipe that was handy.
          Do you think it will run long enough just to see if the rest of the power head is
          “viable”?           If it does, then maybe it’s worth finding a good crankshaft for.

          Should I put the two seals with lips opposing?

            Nice work! Suppose you made the inner ring in steel and heated it to shrink it onto the shaft. Could be a permanent fix?

              Well, that looks like a pretty slick fix indeed….
              You speak of the powerhead being viable…The crankcase is split now, why not just pull the pistons out and have a look….Measure everything up, give it a nice hone job and rering…Might as well only put it together once and be done with it…
              Dang, you just can’t get a break buddy…..This old dog is a real fighter indeed…

                This 40 hp being manual start, and me getting older every day, I don’t see
                me using this motor long term, even if it does run good. Therefore
                I don’t have the desire to throw more money into a sinking ship, lol.
                I rebuilt the lower unit, new bearings, etc., and may keep the motor
                just to have that on hand, as the lower unit apparently is from
                a 25 hp Evinrude, which looks like it will fit my RDE-17 Johnson nicely……
                that motor I do intend to use.

                  Wow that is a nice job on the speedie sleeve! A light coat of JB weld under that puppy and she’ll be good for another 50years! Man there are some talented people out there.

                    That is one of the seal puller I will be adding to my tool list… hoping to have some by the end of the year….but we all know how that works…

                      I used some “Loctite” on the sleeve.
