I am working on my 14' jon boat my uncle gave me and am in the process of wiring the electronics in which I have never done before. In the stern I have a Mercury 20 HP electric start, a Lowrance Elite 4 and the stern light. Could I (should I) wire these all directly to the battery in the rear? The Lowrance has an inline fuse, should I also add one for the stern light? If so, what amp fuse would be best? In the bow, I have a 30lb thrust Minn Kota and the bow light with a separate battery. Also wire these direct? Any help would be appreciated!
