Sierra 18-2996-9 Outdrive Seal for OMC Stern Drive Applications, Pack of 5

The Sierra 18-2996-9 Outdrive Seal is designed for use in OMC stern drive applications, sold in a pack of five seals per package. This aluminum seal is built to meet or exceed the specifications of the original equipment part it replaces, giving boat owners a reliable option when servicing outdrive components. Selling seals in a multi-pack lets technicians and owners keep spares on hand for routine maintenance or replace a full set in one service session rather than ordering single units repeatedly.

Each seal is finished in gray and constructed from aluminum for durability in the marine environment where outdrive seals operate. The 18-2996-9 is cross-referenced to several widely used industry part numbers, making it straightforward to identify as the correct replacement when working from an existing part number rather than a brand name. The compact package (6.46 x 5.83 x 0.67 inches) ships as five individual seals, each measuring approximately 6.5 x 4 x 1 inches, at a total weight of 0.03 pounds.
