I have a 2000 Johnson 115hp that will not fire on the bottom 2 cylinders. I've replace both dual coils installed a new stator and optical eye. But still no fire on the bottom two plugs. Whats crazy is if i swap the power pack wires from the bottom coil to the top coil the bottom coil still has no fire? So I'm getting voltage from all 4 outputs of my power pack. I've replace the bottom coil with another with the same results. Has anyone every experienced this?
