I have a 1998 40HP Mercury Tr
I have a 1998 40HP Mercury Tracker that starts well but begins to run rough at about 2500 rpm. The vibration from motor is severe from about 2300 to 3000a rpm. I have rebuilt the entire fuel sytem an now think it is a problem in the ignition. How do I check the spark coils? Does anyone have other ideas about what I can check.
