Same. Had no idea what I was missing.
I have a Honda 8hp kicker on my little Lund.
It does 2/3 of the trolling work.
I supplement the Honda with my Terova.
The ipilot does the steering chores.
Allows us to stay on course while rigging and netting fish.
I added 2 more deep cycle batteries in parallel to the original 2, along with a 2nd on board charger for them.
Now I have 2X the trolling time.
Added about 200 pounds to the bow though.
