Abstract
A marine propulsion device includes a propeller, a propeller shaft, a bushing, a damper, and a spacer. The propeller shaft supports the propeller. The bushing is between the propeller and the propeller shaft and is unitarily rotatable with the propeller shaft. The damper is fixed to the bushing to transmit rotation of the propeller shaft to the propeller. The spacer is spaced apart from the propeller in a back-and-forth direction in front of the bushing to position the bushing in place with respect to the propeller shaft.
