Hi All, I am kind of new to outboards. I just got a small fishing boat with a 93 Mariner 9.9 on it. I am only getting spark from one cylinder. I swapped the 2 coils around and the problem stayed in the same position. Coils ok. I removed the switch box and while examining it quite a bit of water came out of it where the wires go in when I turned it upside down. I am thinking this is my problem but would like some other opinions as the box is about $200. Is there some way to test it easily or the trigger coil?
