Ensure a proper seal on your gearcase drain and vent screws with this New EMP Drain Screw Gasket. Designed to meet or exceed OEM specifications, this high-quality replacement gasket helps prevent gear lube leaks and protects internal gearcase components from water intrusion.
Drain screw gaskets are a critical maintenance item and should be replaced whenever gear lube is serviced. Reusing old gaskets can result in slow leaks, water contamination, and potential gearcase damage. This EMP gasket provides a reliable seal for a wide range of sterndrive and outboard applications.
This gasket replaces OEM part numbers 311598 and 3852105 and fits numerous OMC, Johnson, Evinrude, and other major marine gearcases.
