Sierra Carburetor Kit 18-7213, Replaces Mercury 810749, Fits 28-34 HP Outboards

The Sierra 18-7213 Carburetor Kit is a rebuild kit for Mercury outboard carburetors, designed to restore correct fuel metering and gasket sealing during a carburetor overhaul. The kit includes an 18-2509 carburetor mounting gasket to seal the carburetor to the intake manifold, helping prevent air and fuel leaks that cause rough idle, hesitation, or hard starting. Sierra engineers its carburetor kits to meet or exceed the specifications of the original equipment components they replace, making this kit a straightforward way to renew carburetor performance without sourcing individual OEM parts separately.

This kit is built for Mercury outboards covered under the 28, 30, 31, 32, 33, and 34 HP applications. It cross-references directly to Mercury part numbers 810749, 8107491, and 8107492, as well as GLM 40620 and Mallory 9-37305, so it can be ordered as a direct equivalent for any of those part numbers. The housing components feature a machined exterior finish consistent with OEM-style carburetor hardware.
