Anyone ever had this happen? I took my transducer off the transom and mounted it to the trolling motor and now on all channels when the troller is running there is "fuzz" on the screen specifically noticeable in the water column on both DI and SI. The sonar "clear mode" isn't as clear and the "max mode" is anything but clear and the sensitivities are turned down to 3. Any thoughts? Help? Thanks.
