2300T Big Bay. Anyone familiar with the prewiring for the trolling motor outlet? I noticed the power feeds run from the plug to under the console. I was wondering it the batteries are recharged by the alternator, during run time, or do they have to recharged at the end of every day...ugh? Is there a connection to the main battery cables under the deck of the boat? If they have to be charged at the end of the day, is their an aftermarket outlet plug I could just plug it in to charge the batteries overnight?
