Marine propellers with compression spring sleeve assemblies
Marine propellers with compression spring sleeve assemblies for driving engagement by a propeller drive shaft may include a propeller hub having an axis of rotation. A compression spring sleeve assembly may be disposed in the propeller hub. The compression spring sleeve assembly may include a drive core comprising a drive core wall. At least one drive rib may extend from the drive core wall. A shaft bore may be formed by the drive core wall. The shaft bore may be sized and configured to receive the propeller drive shaft for driving rotational engagement by the propeller drive shaft. A drive sleeve may be drivingly engaged for rotation by the drive core and drivingly engage the propeller hub for rotation. The drive sleeve may have a drive sleeve body. At least one axial deformation element may have at least one deformation passageway in the drive sleeve body of the drive sleeve. The axial deformation element or elements may be oriented substantially parallel to the axis of rotation of the propeller hub and substantially encased by the drive sleeve body.

Propulsor assemblies having wear resistant snubber
A propulsor assembly for a marine drive has a propulsor, an adapter having a stem which supports the propulsor, a wear resistant snubber on the stem, and an elastomeric member which is sandwiched between the wear resistant snubber and the stem, the elastomeric member being configured to bias the wear resistant snubber radially outwardly into engagement with the propulsor.
