I have a dual battery setup. Old wires need replacing. Had a sluggish crank and warm terminal. Not proceeding further until new wires in place. Both batteries are in the stern. Have a full transom sea drive. Any good online deals for tinned 2 AWG wire? West Marine wants an arm and a leg for ancor. Should I think about moving the batteries at this time? I know some have relocated the batteries forward. She is also in need of wiring upgrades, a bus at least. All the hot wires run straight to battery terminal now, would like to clean it up.
