Sierra 18-7006-1 Carburetor Gasket Kit for Mercury 3.9 HP KB-7A, KB-7B and 4 HP KB-10A Outboards

The Sierra 18-7006-1 Carburetor Gasket Kit supplies the full set of gaskets needed to rebuild the carburetor and fuel strainer assembly on select vintage Mercury outboards. Rather than a full carburetor rebuild kit with a needle, seat, and float, this kit is a dedicated gasket set covering the carburetor flange, mounting surface, bowl, strainer cover, and filter cover, giving a technician everything required to reseal the carburetor circuit during a rebuild or leak repair without sourcing individual gaskets one at a time.

Each gasket is sized to the original equipment carburetor mating surfaces used on the Mercury KB-7A, KB-7B, and KB-10A carburetor models found on 3.9 HP and 4 HP (1 cylinder) outboards. The kit is manufactured in the United States and is built to meet or exceed original equipment quality, making it a reliable choice for restoring a proper seal at the carburetor flange, bowl, and strainer without leaks or vacuum loss.
