Folding Propeller for Boost Fin

Stripped the hex screws and had to drill out. 4th is a stud stuck in plastic. Will leave and do with 3 screws. The hex wrench in package was way to short. Inch longer would work.

Spins faster than standard propeller with cage. A lot less kelp and seaweed trapped. I use two boosts. One with and one without folding propeller on 10 ft. Longboard.

Have not used it yet but seems to be a great idea although a little expensive for what it is.
