It restores proper propeller shaft alignment and allows routine maintenance thanks to its greaseable design — provided your transom has a grease zerk. Before ordering, compare OEM numbers, drive model, and serial ranges to confirm compatibility.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this bearing restore sterndrive alignment?\u003c\/h3\u003e\n\u003cp\u003eThe bearing replaces worn or failed gimbal bearings that let the propeller shaft wobble or sit out of alignment. Proper alignment reduces vibration, wear on seals and coupling components, and improves drivetrain longevity.
