Did a couple hours work on a friends outboard and got several old outboards in exchange. One looked like a pile of crap but beneath the crap lied a 1917 Evinrude model AA 4-stroke 2 cylinder. A fairly rare motor made for 2 years and considered a boat anchor by those that had them. It was only one of 4 motors given to me but it was the one I saw immediately in the pile of old worn out motors. The tank was crushed and rotten through. The mag plate was missing. The carb, intake and exhaust are missing. But this was the infamous Evinrude flop of the early 20th century. I couldn't scrap it so I saved every nut and bolt and piece I could. I am starting to reassemble it now but it's fairly incomplete. Been told by some knowledgeable people that I will probably never get the needed parts for it. People have offered to buy the parts but again, I don't want to scrap it. This motor is too unique. Advanced for it's year, actually too advanced and difficult to run. In disassembling this motor I found a crank with a gear on the top that runs a camshaft that operates a two-valve intake system that also runs a 2-valve exhaust system. This motor us different in that it has no coil or mag plate. It has a date correct brass timer with wiring that would go to a buzz box or batter coil. The entire lower unit is brass, the motor crankcase a combo of brass and cast iron. It is missing some very difficult parts to acquire. It is missing it's Kingston 5 ball carburetor marine application. It is missing 1 cylinder, 1 piston, 2 connecting rods, intake and exhaust, the mag plate and coils and probably a few other parts but those are the majors. I unsoldered all the brass parts from the gas tank and saved them. It's too cool to scrap and so I have resigned myself to waiting and watching for parts. It's worth it. Oh and did I add, it has a reverse rotation prop set up. Only one I've seen and different that all the literature. Would love to hear opinions on what to do with it. Been blasting and restoring it. Here it is so far.
