Sierra Outdrive Seal 18-2516-9, Pack of 5, Fits Bravo Drives

The Sierra Outdrive Seal, part number 18-2516-9, is sold as a pack of 5 seals for use on Bravo drives. Outdrive seals like this one are installed at the drive unit to help keep water out and lubricant in around rotating and mating surfaces, protecting internal drive components from water intrusion and preventing lubricant loss. Because this part is sold in a pack of 5, it gives boat owners and marine technicians enough seals on hand to complete a full outdrive seal replacement or to keep spares in stock for future service work.

Each individual seal measures 0.39 x 0.39 x 0.39 inches, a compact size consistent with the small sealing points found within a stern drive unit. The part is manufactured by Sierra, a long-established supplier of marine replacement parts, and is cataloged specifically for Bravo drive applications.
