Sierra Exhaust Leg Seal 18-2537, Replaces 324937, Pack of 2

The Sierra 18-2537 Exhaust Leg Seal is a round rubber seal used where the exhaust leg meets the engine or exhaust manifold on marine engines, sealing the joint to prevent exhaust and water leakage. It is sold as a package of 2 seals, so both required seals are included in a single purchase rather than needing to buy two separate packages. Sierra engineers this seal to meet or exceed the performance of the original equipment part it replaces, and it is built for the harsh marine environment where engines see sustained heat, vibration, and exposure to saltwater and moisture.

This exhaust leg seal directly replaces OEM part number 324937. Installers use it during exhaust leg or manifold service, gasket replacement, or general maintenance where the original seal has hardened, cracked, or begun to leak. As with all Sierra parts, it is manufactured to a consistent quality standard, and Sierra supplies OEM engine manufacturers and boat builders with parts of this type on a regular basis.
