Abstract

See full text

A propeller hub assembly for a marine drive having a propeller shaft is provided. The propeller hub assembly includes a first hub portion having a first main body and multiple propeller blades extending radially therefrom, a second hub portion, wherein the second hub portion is coupled to the first hub portion, and a damper hub portion, wherein the damper hub portion is coupled to the second hub portion. The propeller hub assembly further includes multiple pendulum masses located within the damper hub portion. The first hub portion, the second hub portion, and the damper hub portion are configured to engage the propeller shaft such that rotation of the propeller shaft causes rotation of the first hub portion, the second hub portion, and the damper hub portion. Oscillations of the pendulum masses relative to the damper hub portion are configured to dampen torsional vibrations of the propeller hub assembly.
