I'm planing to replace most of the small wiring from the console to batteries. Most of the ones on here are two short n I can't move the battery over to one side to add two more. The previous owner added things and didn't remove unused wires. So I want to clean up n redo what I actually need. So what ga size and colors. And is there a color for specific things on the boat. Also need to run a dual wire for the bow light what ga is recommended for that. Thanks in advance for any help.

I would think that 14awg would be fine on a boat. It'll hold 15 amps continuously without heating up and I doubt you have any loads that big on the boat. I'm assuming your boat is less than fifty feet long here.
