Parts Desk Insights
Best Use Case: Use during routine lower-unit oil changes. Verify the gasket and drain-screw mating surfaces are clean, then install the drain screw with the correct gasket.
Common Issues: If the gasket is damaged or reused improperly, it can lead to seepage after service. Always confirm you have the correct replacement gasket (18-4698) for a proper seal, and avoid over-tightening during installation.
