I decided before I bought a bigger trolling motor I would try one of these High Performance Props and see how it works on the Minn Kota. I know I've ready several different things on them, good, and some bad about overheating the motor. My warrently is out anyway, so thought for 29.00 I would give it a shot and see how it works.
I would be really interested when you get one if it helps with reverse thrust. My only real complaint with my MK40 is reverse is totally useless even on high.
