I have decided to keep my 2007 170CC a couple more years until I can afford the 23 Footer I have my eyes on so I want to upgrade my current 55 LB trolling motor to an 80LB 24 volt model. I currently run the 55LB model on 2 batteries in parallel. Do I need to upgrade my wiring from the plug in the bow to the batteries in my center console or is the current wiring OK? I Know I have to re-wire the batteries in the console in the 24 volt pattern. Thanks as always.
