Hello,
I have a 1985 merc 50 hp that starts and runs great but can’t get up on plane. At first I had assumed it was a dirty carb because the boat had sat awhile so I have cleaned the carbs multiple times.. I have determined there is intermittent spark on cylinder 3 and no spark on cylinder 4. I have replaced the spark plugs and swapped coils to ensure that the coils are good. I’m assuming it’s not the stator as there is still strong spark on 1-2. I have replaced the wires coming from the trigger as the insulation was rotten. Any help would be great!
