1982 35hp Evinrude no spark both cylinders

[major]

This morning tried to start the motor. No spark either cylinder. What could be the single point of failure or the most common cause to get me started?

Powerpack 9 out of 10 if you suddenly lose spark on both cylinders.----Cheap and a quick install in minutes.
