Service your gearcase properly with this New EMP Drain Screw and Washer assembly designed for OMC Stringer, Cobra, and King Cobra sterndrives. Manufactured to meet or exceed OEM specifications, this Allen head drain screw provides a secure seal when servicing or replacing gear lube.
Drain screws and sealing washers are critical components in maintaining proper gearcase lubrication. Over time, threads can wear and sealing surfaces can become damaged, leading to leaks or water intrusion. Replacing both the screw and washer during maintenance helps ensure a tight seal and protects internal gears from contamination.
This assembly replaces OEM part numbers 318544 and 912624 and fits 1978–1993 OMC gearcases.
