No spark 1985 Johnson 150

There's a bunch that don't make sense to me, reason for not suggesting deeper.
Normally if the lone fuse is bad, you won't get anything related to the control box to work. The trim, the choke (primer) or the starter. That fuse basically works everything related to the harness.
Bunches of stuff just didn't sound right or at least I didn't comprehend it.

You know, I take that back.
My son in law couldn't get his engine to start and I found out it was that fuse.
He couldn't tell me he had shorted anything or not. Normally if the key switch is turned on and you short anything it will blow that fuse.
