Thats a good card but for big 4 lakemaster is better. And if your looking to link it to a trolling motor you will need to be looking at the ipilot link set up. Also for where you fish I’d bite the bullet and get the new ultrex trolling motor with foot pedal and ipilot. That way you could sell old motor and offset some of the cost. Snubbys is running one and its pretty slick.
