Sierra Exhaust Elbow Gasket, Replaces OMC 907764, 2-Pack (18-0104-9)

The Sierra Exhaust Elbow Gasket (18-0104-9) seals the exhaust elbow on OMC exhaust manifold assemblies, providing the gasket surface needed between the elbow and manifold to prevent exhaust and water leakage at the joint. This gasket is sold as a 2-pack, so buyers get a matched pair for the job in a single purchase rather than ordering individual gaskets separately. It directly replaces OEM number 907764, making it a straightforward drop-in choice for anyone servicing an OMC exhaust manifold and needing the correct elbow gasket without hunting down the original part. Because it is designed specifically for this application, it is sized and shaped to seat correctly against the mating surfaces of the exhaust elbow and manifold, supporting a proper seal when reassembled with correct torque on the mounting fasteners. At just 0.04 pounds, the gasket set is light and easy to handle, ships compactly, and is inexpensive to keep on hand as a maintenance spare. Whether replacing a gasket that has hardened, cracked, or begun to leak with age and heat cycling, or performing a routine exhaust elbow removal for inspection or cleaning, this gasket restores the seal needed for proper operation.
