I have a 1985 mercury 50hp. Recently the #3 and #4 cylinders stopped firing. I ruled out coil and decided it was the power pack. It still had the same problem. Next I changed the trigger and then the stator. I still have the exact same problem. Compression is good, plugs are new and all plug wires are good. I have run out of ideas. Any tips?
