I have recently started to upgrade my onboard electronics. I have acquired a new Solix 15 MSI G2 (for bow) and a used Solix 12 MSI G3 (for console). In process of wiring them up now with 10/2 ga wire. One set to run from bow to battery independent of a 2nd set from console to battery. First question, is the 10/2 ga wire adequate? Second question, will my 31 group starting battery be adequate for both graphs and on board pumps? I don't tournament fish anymore, so using live wells is kind of a mute point and the bilge pumps are as needed. As always I'm appreciative of your replies.
