I have a 1992 Mariner 100 HP that I just replaced the switch box and plugs because #2 cylinder was loosing spark when cold.It ran great for about 35 minutes then died out on me when i got back to the dock I got it going but now it wont idle and two bottom cylinders are arcing spark right through the spark plug boot and there is no change in engine when they are shorted with test light.
