Sierra 18-7770 Carburetor Kit - Replaces Mercury 84456M, Yamaha 689-W0093-02-00

The Sierra 18-7770 Carburetor Kit is a replacement rebuild kit for Yamaha outboard carburetors, built to meet or exceed the quality of the original equipment part it replaces. It is designed as a direct interchange for Mercury 84456M and Yamaha 689-W0093-02-00, 689-W0093-00-00, and 689-W0093-01-00, so it fits carburetor housings originally built to those part numbers. The kit ships as a single unit and includes the components needed to rebuild the carburetor it is intended for, making it a straightforward option for routine carburetor maintenance or repair on the applicable Yamaha outboard engine. The exterior finish is machined for a precise fit against the mating carburetor housing. At 0.05 pounds, it is a small, lightweight kit suited for do-it-yourself installation without specialized tools beyond standard carburetor service equipment. Sierra backs the part with a limited warranty. Because the kit is cross-referenced to specific Mercury and Yamaha part numbers, it is best suited for outboards that originally used one of those carburetor components; buyers should confirm their existing carburetor's part number matches one of the replaces numbers below before ordering.
