      Everything is cleaned up. Starting with the gear case as it’s new to me. Full of grease — along with a little 60+ year old water. Someone has been in here before me as one shim was in front of the disc and one was behind it. The pump eccentric is keyed to, and driven by, the prop shaft. Everything looks good except for —– the key for the pump eccentric. It’s a #2. There is only one size smaller. Looks to be the weak link in this system. A water pump failure seems likely if they had kept using it. The rest appears to be in really good condition. 

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

        I am always amazed at how well that old black grease protects the gearcase parts. I have take apart many with very little damage.

        Great pics, Tubs!

          Nice project Tubs. Keep posting progress pics!

            Tubs, it’s coming along nice.
            It looks like I had to put a new woodruff key in mine as well.

              Looks like you needed to replace the spring as well.

                Hammered the muffler can over a pipe to get the dents out. The smaller one was pretty deep. It came out better than I expected. Used some sockets for the dent in the pipe.

                The fuel line has become separated from the sediment bowl. Trailer Ride? Sediment bowl nut has evidence of contact from player jaws. Contents in the sediment bowl may explain why.  Smoothed out the nut as best I could.

                Cleaned up the magneto. Points are OK. The coil tested good. When testing a condenser, if its leaking, the needle could be anywhere in the green.  Shorted, somewhere in the red. I’ve never had a condenser do this before.

                    Yup it works now!  I never seen a condenser do that either.  Puzzling for sure.

                      I could just get the motor to turn when I got it but now it was stuck. Took a 50/50 mix of gas and oil and put about 8 oz. in the crankcase and some in the cylinders. Sloshed it around once a day and after a few days it would move again. One half of this exhaust port was almost totally blocked with carbon. After cleaning it out, I positioned the piston so I could check the rings. Both were stuck hard. I was hoping not to have disassemble the power head but with all the carbon in this motor it seemed to be necessary. Turned out it’s a good thing I did. The wavy thing, I’ve been told, is a back fire suppressor. They can break up, like this one has, and go into the crankcase. As you can imagine, that is not a good thing. Even if you find them to be in good condition you should remove them. The rings freed up pretty easily except for the top ring. It was only stuck in the area of the exhaust port. It took for ever to get it free without breaking it. Piston and cyl. both look good.

                        Looks like it will be ready to run way before test barrel
                        is ready…….. probably 2-1/2 months here!
