"I have a 1989 40hp mariner/yamaha twin cyl, twin carb oil injected engine with no spark. I have replaced coil pack, plugs, disconnected the kill wire, removed the flywheel and checked the pick ups which appear fine. Still no spark? Can anyone provide some guidance as to how I can carryout further diagnostic checks to establish what may be the problem."
