Your Mercury deserves better than cheap aftermarket parts that fail after one season. This genuine NUT (3/4-16) delivers the reliability your engine was built for.

Engineered to Mercury’s rigorous OEM standards, this component ensures reliable operation across all engine RPM ranges. Part number F1968 is manufactured to exact Mercury Marine factory specifications for precision installation and optimal performance. Constructed from premium marine-grade materials designed to withstand harsh saltwater and freshwater environments.

Cut-rate alternatives might look similar, but they’re not engineered to Mercury’s exacting standards. Part F1968 delivers consistent performance because it’s built right — the same way Mercury does it at the factory.
