I have a 65 HP johnson, around a 1985 model, that when I pulled it out this spring started right up. I had ear muffs on it but I think they were not on right and the motor overheated. After about 10 minutes the motor died and I found I had no spark on all three cylinders. I did notice some black tar looking stuff that could have leaked from the coils. I have no problem buying another stator if I could be sure that it is bad. Is there anyway to test it? I would hate to spend $200 plus to find out that it was not the problem. Any help would be greatly appreciated. Thanks.
