The SIERRA 18-3200 propeller shaft washer is a critical drivetrain component that ensures proper sealing and stabilizes the propeller on the shaft. As a high-quality replacement part, it is designed for outboard and sterndrive engines, including popular MERCRUISER and MERCURY configurations. Due to the wide variety of engine configurations based on production year and version, we do not provide a specific list of compatible models. We recommend verifying fitment by comparing the catalog number 18-3200 with the original equipment (OE) part number found in your engine's manual.

Installation and Maintenance

Proper installation of the washer is essential for safety and performance. Always clean the propeller shaft of corrosion and old sealant before installation to ensure a perfect fit.
