Thank you for the replies. I have a 31 AGM. I have two 9 Helix and one 12 Helix. I really only run one of the 9’s and the 12. But, I use to run all 3 often and never had a power issue. I charge the boat each trip and maintain it. I guess it could be the wires, but I find it hard to believe the Boat Center wouldn’t have the proper wiring when they rig these boats all the time. My connections are good and solid. Maybe the outboard or kicker motor starter is drawing?
