50 hpw mercury cylinder problems?

Question

To the person who answered my question. You stated that it could be the trigger or stator. What about the coil or power pack?

Answer 1

I wasn't the one who answered your question the first time but I think you might be right. I think those motors have 2 coils, with 2 cylinders sharing a coil. Since you have no spark on 2 cylinders maybe the coil that supplies that spark is dead. I am not sure how to test them but one way would be to switch the coils and see if the spark moves to the cylinders that are dead now.
