10-Pack Fill/Drain Screw Washers For Johnson/Evinrude/OMC Outboards – Replaces 311598, 3852105, 777517

Doing a gear oil change on your Johnson, Evinrude, or OMC outboard or sterndrive? Don't reuse that old, crushed washer! This 10-pack of replacement fill and drain screw washers is exactly what you need for a leak-free seal. They're direct replacements for common part numbers like 311598, 3852105, 777517, and also fit Sierra equivalents 18-4248 and Mallory 9-60408. Made from durable material to withstand oil and the marine environment. Having a pack of 10 is super smart – use a fresh one every time you change the gear oil (which you should do regularly!), and you'll always have spares in your boat's toolbox. Installation is simple: just remove the old washer, clean the screw and mating surface, pop on a new washer, and tighten the plug to the proper torque. A cheap and essential part of routine maintenance to keep your lower unit protected from water intrusion.
