      The cork seal was intact in this gear case but was no longer tight around the prop shaft. I just made, and added, a leather seal on top of the cork one. Here is a link with some tips on how I make gaskets. https://youtu.be/I0FrFA__n00?si=ON_CXt34_b2EvVql

      A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

            That seller Tubs links to put together a very impressive gasket set complete with new stainless fasteners.  Almost makes me want to rebuild one.

              Thanks for the info!!!!  I will try and make a leather seal.  What thickness do you use?  I will get some leather off Amazon.  Also, would you suggest I TRY and replace the cork as well?

              Thanks, Terry

                He does very high quality work.  I was very pleased with my purchase.

                  I would be using all leather myself. I used 5-6 oz. but that is what worked for me.

                  OK, I made a new leather gasket.  Still leaks a drop or two.  Maybe it will quit after it swells up.  It’s MUCH better, Thanks!

                  Another issue, I now have a sever fuel leak out of the top of the carb.  It is where the float pin is.  Any suggestions?  I did recoat the float as suggested by an earlier post. Is there a diagram some where so I can see if I put it together correctly?
