Abstract: An improved clutch assembly for use between a propeller and a propeller drive shaft. A bushing preferably in the form of an internally splined tube is adapted to fit over the splined output end of a drive shaft. One or more longitudinally raised ridges extend along a portion of the tube exterior. At least one radial flange extends at least partially around the tube exterior, spaced from one end of the tube. At least one elastomeric cushion, having the configuration of a radial tube section, engages the exterior wall of the tube between ridges. The diameter of this assembly is such as to allow insertion into a propeller bore with a tight friction fit between the cushion and the interior wall of the bore.
