3d printed propeller on drill / trolling motor / boat

yes it sort of works, but it is hard to control. This can be solved with a thicker rod bearings, and a flat steel plate in the water as a rudder or keel. Other than that it has enough power and will move at around 5mph approx.
I did this project on Mar 15, 2020. Fun little thing. But am going to upgrade this to a gas powered weed wacker and steel propeller.
The 3d printed propeller was made with PLA filament.
