A friend of mine has a 97 model 40 HP Force outboard that has a problem. There is no fire to the bottom spark plug. We took the coil off the top and put on the bottom, no fire. Replaced the wiring harness, no fire. Replaced a small electronic box just above the solenoid and still no fire. About the only thing we haven't changed is the stator beneath the flywheel. Question is could that be where the problem is? The upper plug fires and the engine runs just on the one cylinder but runs somewhat rough. Any and all suggestions greatly appreciated.
