hello all, i have a problem. i have a TN25 1950 5 hp johnson and one of my coils is bad. the problem that i have is that the coil is not the one that everyone has a replacement for. most replacements are flywheel magneto coils thatface the flywheel for the magnets. my magneto is a metal disk with magnets that slips down over the crankshaft and the coils face instead of the flywheel. hope thats not too confusing, hard to explain without a drawing. anyway... does anyone have any idea of where i can find one of these coils or has a way been devised to "create your own" using the old coil??? any help would be greatly appreciated. thanks!!!!

Could try laingsoutboards . I know new ones are NLA pretty well everywhere, but they were far more reliable than the ones you see replacements for everywhere so you can go with used ones. Vintageoutboard may be able to help to.<br /><br />Are you certain your coils are bad?

i've tried everything that i can possibly think of to test the coil. cleaned all the connctions, changed the condenser, checked continuity on all wires and plug wire. placed the other coil in its place and it worked. i don't know exactly how to test the coil itself outside of the armature, but if you have any ideas i would love to hear them. i'm willing to try just about anything. thanks.

That does it for me. :) <br /><br />I thought you had two non-functional coils. Good luck finding a replacement. They shouldn't be too hard to find - I'm suprised TCOutboards didn't come through for you.<br /><br />PS - if you have an old lawn mower shop around, try taking one of your coils to them. I think they were used in some real old lawn-boy engines back when OMC owned them too. Don't let them know they're from an outboard.

No trouble at all. If you are looking to make one, don't forget to make sure you've got the right polarity when your done. I can tell you that winding your own is not a good idea - that one was likely made with a zillion turns of 1/2 hair-width wire with paper insulation between layers.
