red is hot, and should be on the left side, at the bottom in that picture. all the other screws on the left side, other than the "hot in" at the bottom, only purpose is to connect the fuses to the "hot bar" and energize them, no wires should be attached to those screws. the middle run of screws, just to the right of the fuses, are the energized connections coming out of the fuses and all "positive out" leads should be connected there. they are not even used in the picture! the bottom screw on the right, where the po has connected the "positive in" power supply wire is actually the negative grounding buss and is meant to connect all ground wires.
the result of the way this thing is wired is the same as if all the hot wires were just twisted together and if all the negative wires were just twisted together and there wasnt a fuse box at all. everything hooked up to it will turn on but WILL NOT BE FUSE PROTECTED. so if there is a short somewhere instead of a fuse blowing and shutting off the power to the short, the shorted wire will remain energized, get very hot, possibly start sparking, probably do a lot of damage and might even make you jump out of your boat so you can tread water and watch it burn!
