Quit running.

I have a 1987 Johnson 140 hp that just shut off. I had just put the boat in the water and was heading to our fishing hole when I got there I backed the throttle down and it just quit. When I got it home I pulled a plug to check for spark and there wasn't any. What should I check next.

Disconnect black/yellow wire from power pack and recheck spark, if have spark key switch or landyard switch bad, if don't then test ignition system on engine.
