314818 OMC GASKET

The 314818 is a gasket used in the bypass cover adapter assembly on Johnson/Evinrude OMC outboard engines. This vintage part was manufactured for 18 HP Johnson Evinrude engines produced between 1957 and 1973. The gasket provides a watertight seal between the bypass cover adapter and the exhaust housing, preventing coolant and exhaust leakage during engine operation. As a discontinued vintage part, availability is limited to specialty outboard restoration suppliers and used parts sources.
