The Sierra 18-2945 drain screw gasket is a replacement sealing washer designed for use during marine gearcase and lower-unit maintenance procedures. Installed beneath the drain or vent screw, the gasket helps maintain a secure seal and supports lubricant retention after service. || Replacing drain screw gaskets during routine gear oil changes is recommended because sealing materials can compress or wear over time. Fresh gaskets help maintain proper sealing performance and reduce the likelihood of fluid seepage. || Manufactured by Sierra Marine as a service replacement component, the 18-2945 gasket is intended for compatible marine engine applications. Verify part compatibility with the engine manufacturer’s specifications before installation.
