Sierra Drain Screw Gasket 18-2430-9, Replaces 26-830749, for Mercury Verado Outboards, 5-Pack

The Sierra 18-2430-9 Drain Screw Gasket is a replacement sealing gasket designed for Mercury Verado outboard engines. Sold in a package of five, it is used to reseal the drain screw during oil changes or service on Verado outboards, restoring a proper seal and preventing leaks around the drain plug. Each gasket is built with marine grade materials to hold up to the marine engine environment. The part cross-references directly to O.E. Part Number 26-830749, making it a straightforward drop-in replacement when the original gasket is worn, compressed, or damaged during routine maintenance. Because it is sold in a 5-pack, it gives owners and shops enough gaskets on hand to cover several service intervals or multiple drain screw locations without reordering. As with any drain screw gasket, buyers should confirm the fitment against their specific Mercury Verado outboard before installation to ensure a proper seal.
