I am taking delivery next week on a new 1652 G3. Prior to the dealer installing the factory vinyl covered aluminum floor and foam, I figured I would have them pre-install a couple wires underneath the floor from the bow to the back of the boat. What gauge wires should I have them pre-install for the following electronics, navigation lights, and fish finder? The boat will be setup for fly fishing with a tiller extension and grab bar, 40/30 jet for river fishing. I will have trolling motor (w/mega down imaging), dedicated lithium batteries, and onboard charger I plan to install in the bow. Any help with suggested # of wires and guage thickness I should tell the dealer to run? Was thinking 2X12 gauge and 2X8 guuge wires. Any thoughts are appreciated.
