Performance & Practical Benefits

A good prop washer may not look impressive, but you’ll absolutely feel the difference when it’s built right. The 887972 Washer helps maintain a tight, secure propeller fit, preventing wobble and reducing stress on the prop shaft. That means smoother acceleration, cleaner shifting between forward and reverse, and a noticeable reduction in vibration.

In everyday use, this washer carries a surprising amount of responsibility — dealing with torque spikes, sudden shifts, and long hours of steady rotation. The hardened Stainless Steel construction holds up incredibly well to those demands. It resists deformation, corrosion, and the kind of gradual wear that can loosen a prop without warning. For boaters who run in saltwater, brackish inlets, or shallow freshwater rivers, that extra resilience becomes a form of peace of mind.

Installation is simple and predictable. The washer seats cleanly, holds its shape under pressure, and locks into its role without fuss. Once in place, it contributes to a secure, balanced prop setup that helps your engine deliver the clean, steady performance it was designed for.

Why Buy OEM

Hardware may seem like an easy place to save money, but anyone who’s dealt with a damaged prop shaft or a lost prop knows better. A genuine Mercury Marine part like the 887972 Washer is engineered to exacting standards — precise thickness, hardness, and fit. Aftermarket washers often rely on cheaper metal or loose tolerances that can deform or wear prematurely, eventually causing far more expensive issues. OEM simply offers the reliability and long-term security every seasoned boater trusts. When you want your prop to stay tight, your power to stay clean, and your day on the water to stay stress-free, OEM hardware is the smart call.
