MerCruiser Cotter Pin 26953
A genuine OEM cotter pin used in Mercury MerCruiser engine and drive assemblies. Cotter pins are single-use safety fasteners that lock clevis pins, castle nuts, and other hardware in place — preventing loosening under vibration and load. This factory-original part is manufactured to Mercury Marine specifications for reliable fit and retention.

Parts Desk Insights
Best use case: Cotter pins are a one-time-use part — they should be replaced any time a pinned assembly is disassembled, even if the old pin looks intact. This is especially important on steering linkages, throttle and shift connections, and trim cylinder anchor points where a failed pin can cause a loss of control. Keep a few spares aboard for field repairs. Order by the part number in your Mercury diagram; pin diameter and leg length are critical to proper retention and are not interchangeable across sizes.
