18-4431-9 SIERRA "EXHAUST ELBOW GASKET" Replaces EVINRUDE & JOHNSON 351325
$11.00
The 18-4431-9 Sierra exhaust elbow gasket is a precision-engineered replacement for Evinrude and Johnson outboards (OEM 351325). This critical sealing component prevents exhaust gas leakage at the elbow connection, maintaining proper back-pressure and engine efficiency. Constructed from high-temperature materials, it withstands thermal cycling and corrosive saltwater environments. Replace during routine maintenance or when installing a new exhaust elbow to ensure a watertight seal and optimal engine performance.
