As stated. Battery is fully charged, 12v to and through starter slave solenoid and circuit breaker. No buzzer or any other activity with ignition switch in ON or START position. Trim motor runs up and down. All fuses OK. None of the panel switches work, no horn, bilge blower etc. I will TS it further tomorrow but if anyone has any suggestions it would be appreciated. Its a 2008 175 Sport, 3.0L, Alpha 1 drive with less than 50 hours.

we will need some more details but it sounds like the things that are connected directly to the battery are working but the other electrical things are not.....what about a bad connection on the battery selector switch?.....

There is a breaker for the 12V power that runs to the dash. Its mounted on the inside of the hull right next to the battery. Under the starboard side rear seat. Just lift up that seat cushion and you will see it. Check if it tripped.
 
Both breakers are fine and have 12v through them. I am going out now to further TS it. I suspect the ignition switch.

i could be wrong but i am not sure that a bad ignition switch would prevent the panel switches from getting power......

You are correct. It was the 50 amp breaker on the engine. I reset it and all is well. Thanks to all who answered.
