Is it a switch or a breaker? Don't have that boat, but I would think it may be a breaker.
Did you flip it? Turn it off and then go through everything and see what does/doesn't work.
I would think it is a master power on off switch so you can shut down power to everything on the boat that is ran through the fuse box. Turn it off and see if anything works. I have one of these but it is on my dash. Make sure to check your boat running lights as you do this, put one pole in and see.
