It fits many Mercury Command Thrust 40–115hp models and a broad range of Mercury FourStroke outboards up to 225hp that use a 1\" diameter propeller shaft. The kit includes all necessary internal components to restore or improve propeller-drive engagement and protect driveline components during impacts.\u003c\/p\u003e\n\n\u003ch3\u003eWill this hub kit fit my Mercury outboard?\u003c\/h3\u003e\n\u003cp\u003eThe 8M0150152 SSR hub is intended for Mercury outboards with a 1\" diameter propeller shaft, covering Command Thrust 40–115hp models and most FourStroke engines up to 225hp when used in standard, non-surface-piercing applications.
