I am sure this has been covered before but I am somewhat new here and missed it. I have a Lowrance Hook 7 on the bow of my Ranger 518 and a Lowrance HDS Gen 3 , 9" unit at my console. Whenever the trolling motor, (Motorguide xi5, 80 lb, 24v) is running I have noise on my bow unit, not my console unit. The noise is proportional to the speed I run the trolling motor. Any ideas.
