Abstract: A propeller hub assembly comprises a driven member having an outer cylindrical housing and an inner cylindrical housing. The inner cylindrical housing is coaxially fixedly coupled and radially spaced from the outer cylindrical housing, and includes a plurality of radially inwardly directed circumferentially spaced ribs oriented parallel to an axis of the inner cylindrical housing. The propeller hub assembly further includes a driving member which comprises a cylindrical member having an axis of rotation. An opening passes through the driving member coaxial with the axis of rotation and is adapted for receiving a drive shaft. The driving member further includes a plurality of radially outwardly extending ribs oriented parallel to the axis of rotation and terminating radially at a diameter substantially equal to an inner diameter of the inner cylindrical housing.
