On occasion the boat will start and run just fine but none of the electronics function, no radio, no bilge, no fan, no electronics period. Don't even know where to start (pun intended).

Make sure the accessory power and ground wires at the battery have a solid connection and no corrosion. If its on occasion, its most likely and loose or corroded connection.....start at the battery.
 
I have the same boat, and this issue presented itself awhile back. Turns out one of the leads on the positive battery terminal had some corrosion and wasn't making a solid connection. Also, regarding the fuse. The fuse to check is "inline" on the smaller of the read wire leads, as the fuses in the engine compartment are for the engine components (see below). What you are looking for kind of looks like this (and in my boat was attached to the bulkhead by the batteries).
