Sierra 18-3204-9 Tab Washer, Replaces 14-76281, Fits Mercury/Mariner 30-60 HP Non-Bigfoot Outboards, Pack of 10

The Sierra 18-3204-9 is a tab washer designed for Mercury/Mariner 30-60 hp (non-Bigfoot) outboard engines, sold in a pack of 10. A tab washer locks a fastener in place by bending one of its tabs against an adjacent flat or nut face, keeping the fastener from loosening under the vibration of normal outboard operation. This washer has a 1/4 inch inside diameter, sized to fit the fastener bore it is designed for, and serves as a direct replacement for the original Mercury/Mariner part.

Because a worn or missing tab washer can allow a critical fastener to back out over time, replacing it with the correct part is a routine but important part of outboard maintenance. The 18-3204-9 pack supplies ten washers, giving an installer enough on hand for a full service job or several repairs without needing to reorder individual pieces. Each washer is manufactured by Sierra and backed by Sierra's customer satisfaction warranty.
