    Mercury 50 Ignition

    Mercury 50 hp, 3 cylinder, OA987473, that has no spark at any of the plugs. I found a master ignition switch on the shifter / throttle housing, but, still no fire. I disconnected the black / yellow stripe wire from the switch box; still no fire. What else could kill all 3? Thanks, J
