I am just a boating enthusiast and like to do my own work in our boat. Our new boat have a dual battery set up and We plan to install the Blue Sea Add a Battery Kit. Looking at the diagram, it shows "fuse" between ACR positive to house and start battery positive. Searched the forum for the fuse rating and wire guage for this set up and cannot find the information. We have a 250hp Suzuki that output 54 amps. Can anyone chime in as to what size fuse and wire guage to install?
