UPDATE. Thank you all for your suggestions and tips.
Turns out it was a 30amp fuse on the engine that was blown. Everything is working. I learned a valuable lesson this week. So glad it was nothing more.
Thanks again.
I accidentally hooked up my 2 marine batteries wrong. See before and after below. Once hooked up wrong I turned the selector switch to both and tried to turn the key to check power and had nothing. I noticed the wires were very hot and turned everything off. I then undid the wires and removed...
