First outing on the boat this year. The passenger bolster switches aren't working. Neither for the seat or foot rests. Also there are several gauges who's lights are out. Is there a fuse panel anywhere on this boat?

Not sure on your fuse location, but grounds, especially on boats can be tricky things. Being that boats themselves are non-conductive, one failed or failing ground wire can reek havoc. See if these devices share a common ground circuit, or maybe a battery. If need be check resistance on the ground wires from the device to the battery. This, of course, after you've confirmed it's not a blown fuse
