I have had it out on the river but yesterday I got to put it to the test on KY lake. (Minn Kota Terrova 80lb 24v with I pilot) I have a 21' Aires bass boat. The wind and waves were ROLLING on the lake to the point of waves just about coming over the bow and casting into the wind was a battle not worth fighting. The trolling motor was impressive. I could engage the "spot lock" and walk to the back of the boat and fish unobstructed and with more room not to fall out of the boat lol. The motor had plenty of power. I was not fishing a tournament so I got out of that into a bay after not too long but still had to work the motor quite hard for 6 hrs and still had plenty of battery left(the trolling motor has a gauge built in that said I still had 3/4 battery left with two optima blue top)
