Re: '71 Johnson 9.9 electric starter . . . possibility?
I don't think there's any way to make a 9.5 an electric start. What are you breaking on the manual start? You could try to piece used parts together, or just buy a used recoil (complete) from Tim's outboard 218-682-2331. Make sure you have your model number handy when you call, as I believe there were a couple minor changes in that motor over the production years in the recoil parts. Good luck!
