Anyone have an idea on how to install a marine 12V system in a boat without one currently? I own a 14' runabout, which at the moment has bow and stern lights, which are haphazardly wired to alligator clips which I assume you attach to a 12V battery. However it's a mess, and I would like to replace it. I will first replace the outboard (extremely old mercury 35 hp 2-stroke) with one which contains an alternator, and I know I will need a battery, but what else, and how does it all go together? I assume a fuse box will be needed at some point? I would like to be able to have running lights, radio, fishfinder/GPS on the system. Any and all help is appreciated!
