...of course it makes total sense that Yamaha would place a fuse in front of all else just in case somebody (me) reversed the polarity when connecting the battery! I traced the wires from the up/down switch on the side of my motor and I found the fuse. Went over to Autozone and replaced my fuse, and now my switch is working as normal! Thanks all for your help, much appreciated.
