40 Mariner all of a sudden no start with key

[HittinSteel]

My early 80’s Mariner 40 has been running great. Last weekend I turned the key to start and got nothing. I check battery strength, cleaned terminals, replaced solenoid, and inline fuse.

If I jump the solenoid, it cranks. If I turn the key and push in for the choke, I can hear it engage.

Good news is it rope starts pretty easily but I prefer the key!

thanks for any input in what to test/ replace next.
