Performance & Practical Benefits

The 41721 hinge pin washer keeps your bell housing pivoting smoothly by reducing metal-on-metal contact. The phenolic material absorbs vibration, resists compression, and prevents corrosion at one of the most critical points of your drive’s steering assembly.

The adhesive backing simplifies installation and keeps the washer in position during assembly. Once installed, it stays put — even under repeated stress from trim and steering movement. The result is smoother operation, less wear on surrounding parts, and fewer service issues down the road.

Why Buy OEM

The Quicksilver 41721 is a genuine Mercury Marine part, made to the exact specs your sterndrive was built with. Generic washers may use inferior materials that break down or deform over time, leading to steering stiffness or misalignment.

Mercury’s phenolic washer is precision-cut, tested for heat and pressure resistance, and designed to maintain its shape and thickness under marine conditions. When it comes to small but vital components, OEM quality ensures everything fits right and lasts longer.
