A two-piece axle bushing (40) for marine propeller (10) includes a first transmission member (50) including an accommodation chamber (52) and longitudinal inner ribs (54) spaced around an inner perimeter of the accommodation chamber (52), and a second transmission member (60), which includes a tube shaft (70) that includes a first transmission segment (71) inserted into the accommodation chamber (52) of the first transmission member (50) and including longitudinal outer ribs (74) spaced around the outer perimeter thereof and respectively movably inserted into one respective buffer space (56) of the first transmission member (50) and selectively engageable with one respective longitudinal inner rib (54) and a second transmission segment (72) connected to the first transmission segment (71), and a shock absorber (80) fixedly surrounding the outer perimeter of the second transmission segment (72). Thus, the two-piece axle bushing (40) of the present invention can generate power hysteresis effects when the engine starts up, reducing vibration due to a sudden high torque and further enhancing marine propeller (10) start-up stability and smoothness.
