Good To Know

Q: How do I know if my drain screw gasket needs replacement? A: If you notice oil leaking from the drain screw or the gasket appears flattened or cracked, it's time to replace it. Regular replacement during oil changes prevents leaks and contamination.

Q: Can these gaskets be reused? A: No, these gaskets are designed for one-time use. Always replace them each time you drain the lower unit oil to ensure a proper seal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
