Fitment Notice
Confirm fitment by drive serial number, drive model, bearing carrier style, propeller shaft arrangement, and exact Mercury/MerCruiser parts diagram before ordering. Bravo and Blackhawk gear housings use multiple seals, O-rings, spacers, and carrier components, and the correct seal depends on the specific lower-unit configuration.
When This Part Needs Replacement
Replace this oil seal if gear lubricant is leaking from the propeller shaft / bearing carrier area, water is found in the gear lube, the seal lip is hardened or damaged, or the bearing carrier has been removed during lower-unit service. It should also be inspected after fishing line, debris, corrosion, or propeller shaft wear is found behind the propeller hardware.
Installation Notes
Inspect the propeller shaft sealing surface, bearing carrier bore, carrier O-rings, related seals, drain and vent screw gaskets, and gear lube condition during service. A grooved, pitted, or corroded shaft can damage a new seal and cause repeat leakage. After seal replacement, pressure/vacuum test the drive before refilling with gear lubricant and returning the sterndrive to service.

Parts Desk Insight
Bravo Three and Blackhawk propeller shaft seals should be treated as part of the full bearing carrier sealing system. If the drive oil is milky or the prop shaft area is leaking, inspect the carrier seals, O-rings, prop shaft surface, drain plug seals, and pressure/vacuum test results together instead of replacing one seal without confirming the leak point.
