    Maybe a dynamic propeller analysis and balance is in order? It can reduce vibration providing the propeller itself is balanced properly and both blades pitched equally.

    The design's stepped end mimics some of the newer ice spuds used to open holes for fishing. They gradually penetrate hard surfaces rather than the whole end trying to go though all at once.

    One of my primary instructors 45 yrs ago (Bill Griffin) always asked what I was going to do if the engine quit - during takeoff, flight, or landing approach. I can still hear him.
