Just out of curiosity- All those older OMC mags 1960 through about 1975, 3 to about 20 hp look very much alike- almost identical in fact. Are they interchangeable? It would make it easier to find a substitute.

Do you know if the mag plates are “common” to all the small hp OMC’s. If they are I could likely source one from around the neighbourhood. If not, I would take you up on your kind offer If you are confident they are not too worn, I don’t need coils as the ones I have are almost new. Where are you and how much do you think shipping might be to Sudbury, Ontario, Canada?

I found an old post by one of your guys called Mumbles “February 26, 2019 at 3:58 pm#169760
The universal mag was used on the 3 and 4 horse motors until ’84, the 6 until ’76, 9.5, 18, and 40 horse until ’73, 20 and 25 horse until ’72. The 2 horse used it until ’86 and the 1.25 and 2.5 horse motors used it from ’87 on.

Remember the cranky Low Tension mag as used on ’74 – ’76 9.9/15 horse motors? It and the Universal Mag were replaced with the superior CD (Capacitor Discharge) Ignition system as time went on.

This gives me the impression that any mag plate from any of the 3-25 hp OMC’s from about 1960 -75 would fit. I’ve got a scrap power head from a 1960 18 hp Johnson that I could swap. Any comments?

Thanks – I never thought of that. I’ll dig out the old 18 hp powerhead.
