    Does anyone have coils for a 1947 KD-15? or know of a source? Can I modify and make a newer style coil work? This motor is 100 percent complete and doesn’t look like it was ran very much. It looks like it sat outside for a good bit, but the exhaust is really clean, mag plate was exceptionally clean, top and bottom. It would be a shame not to keep it original. Gonna use it for my main runner on a late 30’s Rhinelander wood boat. Any help is appreciated

    Are you sure the coils are bad? These coils are very well made, and I have only run across one that was truly bad. I suppose it is possible that both yours are toast, but I would clean all my connections and test them again before trying a swap. JMHO

    I agree with David. Getting the wiring on correctly with the insulating washers can be a bit tricky and making sure the caps are in spec and not leaking will help to insure a good spark. Clean and polished points will also help as these motors didn’t have the strongest magnets in the flywheel.

    I checked it with a meter and the primary pegged out secondary doesn’t budge the needle. I think I’m gonna unsolder everything (ground wire points wire kill switch) completely remove the coils and try again. I was thinking the same thing, they looked pretty solid built so what’s the odds they both went bad? I’ll check a good set with my meter but it’s new so shouldn’t be a problem, although it is a cheapo but I really like it, it has the needle and a large face on it. I hope I’m wrong, as I say I’d like to keep the mechanics original.

    Well I removed the coils and tested them again , still nothing. Primary good, secondary….. Nothing. So back to my original question I guess. What are my options?
    Like I said looks like it sat outside a LONG time, so maybe moisture got the best of them.

    I had a bad coil in my K+80, same basic motor as yours just older. I removed the old coils and put omc universal coils on the laminates.

    Do you use all of the laminates from the old? As in the square part that goes thru the center of the coil plus the outer laminates that screw to the mag plate? Is there a part # for these or is it just the coil that fits all the 50’s motors ?
