All Brass Prop Knocker - Fits 2-1/4" And 2-1/2" Shafts

• 1-3/4 - 5 threads

• CNC Machined from All Brass with perfection.

• Threads onto the shaft, excellent for splined shafts.

Simply screw it on in place of your prop nut and give it a knock with a hammer. It will jolt the prop loose from the shaft.

Then, unscrew the knocker and pull off the propeller! Yes; it is that simple.
