Re: 1959 Johnson 35HP RD-21 electric starter question

I think your original starter should have an 11 tooth pinion and MDO-4002M stamped on the housing. P/N’s 385401, 392133, and 380238 are possibilities. I do have a pile of various starters both 6V and 12V so I’ll measure some when I finish doing yardwork.
