Description
Your Mercury deserves better than cheap aftermarket parts that fail after one season. This genuine WASHER, STEERING BRACKET SPACER delivers the reliability your engine was built for.
Designed and manufactured to Mercury Marine OEM standards, this seal ensures reliable operation across all engine RPM ranges. Part number 20959 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 20959 delivers consistent performance because it’s built right — the same way Mercury does it at the factory.
