"I have a late 90's 25 hp
"I have a late 90's 25 hp 2 stroke mariner outboard, I have no spark at the lower cylinder and I have spark at the top cyl. I swaped my coil wires over then got spark at the lower cyl. and not at the top cyl. I suspect its my switch box but not 100% sure. Everything else with wiring seems ok. Anything I might have missed??? Any help would great."
