Thanks Victor,
Any idea which specific model plane prop it is and where it can be found?
You have to wonder about this kind of thing. You would think that Minn Kota has put a lot of R & D behind their props, and I'm sure they will tell you that what they have supplied with the motor is the best trade-off between thrust and energy efficiency. If I find I need a bit more power, I'll look into changing the props.

Apparently, some people have swapped out the trolling motor prop in favour of a large model airplane prop to change the pitch and give a bit more push. Just a thought.
