you might, but might not. If you can run another set of +/- wires up to the front without much trouble but on the opposite side of the boat from the TM wires, that will reduce the possibility of interference. I ran a new set of power wires up to the front under the floor of my Tracker PT175 under the floor a couple of years ago. You can use one of those wire snakes/puller that electricians use to see if your boat has the open space to do it fairly easily
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
