I have a 1978 800 mercury 80hp that has a miss under a load. I have replaced all the coil packs and plugs and plug wires, done a compression test with all cylinders being around 95, I’ve rewired from the key switch to the motor. The miss started out very small but is getting worse every time out. I have noticed that the previous owners have cut the 2 yellow wires going to the rectifier and I can’t even find the rectifier.
