Im getting interference from my outboard I believe. I got rid of interference from the trolling motor by installing a ferrite ring that humminbird sent me. My question is after looking at the type of interference I have, I am realizing it could be the location of my transducer. Dealer said that where they install them all the time with no problem. I am posting pics of the transducer placement and the interference I am getting on the dash mount Hummindird 998. Transducer is mounted on jack plate. It usually appears on the screen when I accelerate. Any suggestions on what it might be?
