Abstract
A propeller assembly is provided in which the propeller blades are adjustable both rotatably and longitudinally. Pitch angle of the propeller blades may be adjusted by rotating the blades in the hub of the assembly. The outer diameter of the propeller blades may be adjusted by sliding the shafts of the blades into the hub of the assembly to a desired position and locking the shafts thereat by means of set collars. The hub of this propeller assembly is split providing for disassembly and removal of the entire propeller assembly from the drive shaft without removing inboard or outboard shaft bearings or other components. The entire assembly is specially designed for simplified construction by the average amateur homebuilder or hobbyist using only a hack saw, drill press and grinder. No casting, welding or machining is necessary.
