Just replaced my intake gaskets and we lost power to the coil. then as we were searching out the answer we lost all power from the key back and keep blowing fuses for the switch. We replaced the cellenoid and have checked everything. it is wired exactly like the port motor. any suggestions?
it is a thunderbolt mercruiser ignition

Check The Emergency Tether switch, Seems to alot of those get pulled off accidently.

Good thought cuz we had that happen once when we were working on the race boat. Looked at everything then I went under the dash.....

The problem hear is he said that he has blown fueses. That would not blow any fuses....

Some place you put power to ground or wired something backwards.

Agreed. Better check and recheck that coil wiring. It's the only wiring you would have messed with so it's probably the problem.
