Hi,
I have a few switches on my 77 Carver with an OMC stern drive and was hoping someone could please help identify these. I've tried googling, but I haven't had much luck. I've tried tracing some of the wiring but I believe they terminate somewhere in the 5th dimension. I'm an experienced mechanic but this is my first boat so please pardon my noob ignorance!
First, I have no clue what aux volts vs. fuel volts are, what are the appropriate use for each setting?

Next, I have a push button and 2 rocker switches that are unmarked and I'm at a loss as to what they do. There's also a sliding lever next to the throttle:

Thanks for any assistance!
