SIERRA Johnson / Evinrude 9.9-15 HP Exhaust Cover Gasket – 18-2853

Sierra 18-2853 is a Exhaust cover gasket engineered for the specified marine application. Johnson/Evinrude 9.9 HP and 15 HP two-stroke outboards using OMC/BRP gasket 318925.

• Exhaust-cover gasket for compatible Johnson/Evinrude 9.9-15 HP two-stroke outboards.
• Replaces OMC/BRP 318925 and cross-references GLM 34320.
• Many applications use two gaskets per engine; confirm the service diagram and required quantity.
• Seals the exhaust-cover joint against exhaust-gas and cooling-water leakage.
• Remove old gasket residue without gouging the aluminum sealing surfaces and inspect the cover for warpage.

Fitment for marine engine and drive service parts can vary by model, serial number, gearcase, cooling configuration and prior component supersessions. Compare the original OEM number and physical configuration before installation, and renew related seals, locking hardware or adjacent wear items when their condition requires it.
