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

• 1-3/4 – 5 threads

• CNC Machined from AllBrass 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.

NOTE: You do NOT have to screw it on far enough to reach the prop hub! May have to wiggle the prop as you are tapping on the harmonic puller.
