No Spark on #1 Cylinder

[river rat]

I have a 1983 70 hp Evinrude that has ran fine all summer, today I went out and the motor would not start.
I found out that the number 1 cylinder did not have any spark, I changed the plug, checked the spark plug wire and checked the ground wire to the coil.
Should I replace the #1 coil or could it have something to do with the power pack?

Thanks

Try swapping ignition coils to see if #1 coil fires on #2, to see if coil is bad.
