A friend of mine has a 2-cyl 45" OMC on a jon boat. The motor has no spark. He assumed that because I race boats I could tell him how to troubleshoot it. He assumed wrong! On my Pro motors it is really simple, the flywheel magnet passes the pickup, the pickup energizes the coil, the coil fires the plug. But under the cowl of his motor there are wires and stuff all over the place. I have no idea where to even start.

Anybody out there have any suggestions where I should start?? Thanks - Tim Chance
