This 100-hour kit delivers just that. The O-ring kit helps ensure watertight, confident sealing throughout the drive assembly. You’ll feel that secure, correct fit the moment each piece seats into place. The aluminum anodes are crucial for protecting your Bravo Three in any environment, especially saltwater, where corrosion can creep in fast if left unchecked. And the gearcase drain seals help maintain clean, steady lubrication changes—keeping shifts smooth and the props turning quietly and predictably. Once the service is complete, the drive feels renewed. Shifts are crisp, engagement is clean, and the whole system runs with the kind of quiet confidence that reminds you why proper maintenance matters.
