314850 OMC GASKET

The 314850 is a powerhead base gasket (GSKT PWHD) used in 4 HP Johnson Evinrude outboard engines, specifically the 4R and 4400 series models from 1969 to 1979. This gasket creates a watertight seal between the powerhead and the crankcase, preventing internal coolant circulation loss and maintaining engine integrity. The part is included in OEM powerhead gasket sets and is available from marine parts retailers. Compatible with vintage small-HP Johnson and Evinrude outboards of that era.
