Re: Fireing
It's unusual for all sides of a magneto type ignition to go out at the same time. Eliminate the kill circuit (black wire with a yellow tracer) or unhook the boat harness from the engine harness. Now test for spark. If you now have spark the issue is from the motor forward. Most likely a bad key switch or bad kill switch.
Remember, if you disconnect the kill circuit and start the motor you'll have to flood it to shut it down. It's better to simply check for spark with the kill circuit disconnected.
