Evinrude 15 hp Big Twin Electric conversion

So when “they” put the chain drive on they did away with vacuum switch? or possibly moved the vacuum switch

That chain drive sprocket looks to me like it came from a electric start model L gravely two wheel lawn tractor. As far as a retro fit of a older (1951 to 1953 ) big twin I looked into this a few years ago with my 1953 Johnson 25. It did not have the rear threaded hole cast in block for the electric start recoil needed. I actually bought a complete1954 electric start Johnson power head, and a 1954 hood with the bulge for starter, Then I thought about it and realized I was just making a frankenstien motor and just destroying a nice original motor. So I did not do it. Much easier to just get a electric start later model.

Yup, I’ve given up the idea! I’ll look for an electric start motor for the future!

Thanks for the confirmation! I guess I’ll just look for another motor in the future, in the meantime get the one I have up and running!

Well, Just in case, Look for the boss as you work on the motor. 🙂

[Shamus]

I sure will. Thanks for the advice.
