Starting battery help in This Old Boat Posted February 6 · Edited February 6 by nathaniel Hi i need a new starting battery this year for my boat and im not too sure what to get. I currently have a interstate 24M-XHD and am looking to upgrade this year. I will be running a helix 12 on it and sometimes a helix 7. I currently run my 2 cannon riggers to my trolling motor batteries but i think i would like to move them to my starting battery so the auto stop feature will work. My engine is a 115 hp 2 stroke. I do alot of bass fishing with my boat along as salmon fishing. I am also looking at possibly getting an AGM battery. Any recommendations would be greatly appropriated.
