Hmmmm, what trolling motor head do you have? i-Pilot or i-Link. If i-Pilot it will not matter what FF you get. It will not talk to the FF. You need the i-Link version.

You will need to go with a Helix 9+. I am looking at installing a Helix 10 on my boat. Should be installing it about this time next month. Here's the compatibility list for i-Link.
