Yeah, Rickie, my console unit was on but I tried changing the frequency on it earlier to eliminate the verticle lines on the bow unit but nothing changed. These lines are only present when the trolling motor is running. They also change or go away at different speeds. I was reading another post that you commented on about the onboard charger. I'm gonna disconnect it from my cranking battery the next time I go out to see if it will eliminate the problem. I like running both units on 455(side scan at console) because I miss things if I run 800. When the transducer was mounted on the trolling motor, the interference would completely fill the screen. It's 1000 times better now.
