trolling motor interfering with sonar?

I put a ferrite bead on both transducer cables with no real effect. I saw this on Garmin site so I’ll add to NMEA cables and power cables. Not holding my breath.
Disconnecting ground from nav lights did not help
The extra cable from the transducer leads is in 1’ loops neatly zip tied and laying on top of the reverse actuator boxes in head compartment. Uncoiling them just to see would be major PITA but right now I can think of nothing else.
I have noticed it is interfering with clear-vu as well. Standard sonar thru factory Airmar is the only thing that is really clear with troller on. Very disappointing

Well shoot. I was sure that would clear things up. Like i said before I had MK powerdrive and 2 garmins with live scope all on the same 12v supply and had no interference. Not sure why Garmin shows ferrite beads on power and network cables also. That’s a new on to me
