I run my 24 volt 70 lb. Terrova with I Pilot pulling cranks anywhere from 1.6 to 2.2 mph. The hotter the water temp the faster I pull them. I started out pulling with a 115 Yamaha four stroke....it would not go slow enough at idle so I put a Troll a Matic trolling plate on it.....and that worked good...I would tie the steering wheel straight with a bungie cord and steer with a 40 lb. trolling motor. Then I traded boats and went to the bigger Terrova trolling motor.
