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.
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.
