My 798ci is mounted on my trolling motor. When I put power on he trolling motor to move forward the screen goes from dark blue to a lighter shade. Is this interference from the trolling motor? If so what do I do to eliminate this?

Sounds like trolling motor interference to me. Now call Humminbird’s Customer Resource folks at 1-800-633-1468 and talk to them about what to do. Generally they will need to know what Humminbird equipment you have on your boat and may have you do some re-wiring or change a menu setting or two. If these don’t help enough they will probably send you a trolling motor interference kit to install on your boat.
