I do have 2 thoughts, of which one I am sure you have thought of….Battery? Second have you tried to re-pair the remote to the motor?
The i-Pilot Link remote is prelearned to the controller from the factory. The top of
the controller has a single learn button to allow additional remotes to be added
to the system. To learn additional remotes:
1. Power up the trolling motor.
2. Push and hold the learn button down. A steady audio tone will
be heard while holding this button.
3. While holding the learn button on the controller, from the remote home screen select:
Settings > Learn and press the OK key
4. If the learn process was successful, the controller will respond with four beeps. In
addition, the Dashboard section of the remote will begin to display motor status
information such as prop speed.
A remote can only be learned to one controller at a time. A controller can have up to
4 remotes learned to it and actively communicating with it.
This one is for the regular iPilot
