Before I retired I collected a number of short shaft parts motors. I thought it would be fun and keep me busy working on these outboards. Just take my time, disassemble them, sort the good parts and then see what I could build. I am a very patient person, but the frustration of trying to disassemble some of these motors was upsetting. Bolts would break, studs were seized, parts were rust welded together, threads would strip, most parts with a spline won’t separate, some aluminum casting just broke into pieces and some clamp bracket assemblies took hours to disassemble. I tried penetrating oils, heat cycles, boiling water baths, even used a BBQ at 400 degrees for 1/2 an hour. Something you would think would take 10 minutes took 2 hours. I filled more garbage cans than parts boxes. Many parts I just gave up on after hours of effort. Others because the part was valuable I spent hours drilling out the seized part. Clamp brackets, steering arms, motor mounts, head bolts were the worst. Dis-similar metals in a part were always a problem. I learned my lesson and from then on I always check before I buy to see if the parts will separate. Or have the seller disassemble it . Sellers that just sell parts can sometimes be a better buy because you see the parts condition and where or not you can use it as is. What has your experience been like? Any special tricks you can share? Any makes or models easier to work on that others? |

For seized bolts or studs, I weld a nut on it. Sometimes it snaps off so I reweld another nut on it until it frees it's self. I've been very successful that way. I started my living in a machine shop and I can't tell you how many times customers would walk in with something they buggered up with broken drill bits or easy outs stuck inside. |

A saltwater motor will really teat your patience! If you can’t weld a nut on and your only option is to drill out then lets hope its a Yamaha! The bolt grade is softer than omc & Merc. I used to keep going up a drill size until I could pick the remaining metal from the threads! I have found now that a Heli-Coil is my best friend and works very well for removal in the future i also ad anti-seize to any and all bolts incase i’m lucky enough to work on it again!! |

Disassembly of old Japanese outboard require great peace of mind. Assembly of American outboard require great peace of mind. |
