A secure propeller is essential for smooth and reliable performance on the water, and the Mercury Tab Washer (14-76281Q) is built to keep it that way. Acting as a critical locking mechanism, this tab washer ensures that your propeller nut stays firmly in place, preventing loosening from vibration and continuous engine operation. Without it, the risk of a shifting or detached propeller increases—something no boater wants to deal with mid-ride.

Designed specifically for Mercury and Mariner outboards (30-60 HP, non-Bigfoot models), this OEM tab washer is made from durable, corrosion-resistant materials that withstand the harsh marine environment. Whether replacing a worn washer or securing a new propeller installation, this small but vital component plays a big role in your boat’s performance and safety.

Why It’s a Must-Have:

• Locks the Prop Nut in Place – Prevents loosening due to vibration and engine torque.
• OEM Fit & Durability – Built to Mercury’s exact specifications for seamless integration.
• Easy to Install – A simple but essential part of routine propeller maintenance.

A loose propeller is a problem no boater wants to face. Swapping out an old tab washer is a quick fix that keeps your setup secure and your ride worry-free.
