Hey guys, i'm about to throw in the towel i think. I have a 45 horse mercury from the 80's. I've done nothing but work to this thing. I normally fish 5 days a week, but I have only been out 5 times in the past 4 months now because of this motor.

I have no spark on cylinder 2. This is a 4 cylinder engine with 2 carbs. I've replaced the plugs, coils, and swapped plug wires and that's not it. still no spark.

I've heard it cannot be the trigger or stator because I would lose fire to more than one cylinder.

Is it the switchbox? Are there any more parts it could be? My mechanic wants 200 bucks for a diagnosis, and I can't see dumping that much money plus parts and labor into a motor that is 30ish years old.
