Description
SIERRA Weber/Carter 4-Barrel Carburetor Rebuild Kit – 18-7749 is a marine carburetor rebuild kit for specific Weber/Carter four-barrel applications, including the 9661, 9770 and 9781 families. Sierra supplies the float, gaskets and O-rings required for a more complete overhaul than a gasket-only service kit.
The kit cross-references several MerCruiser service numbers, including later 8M-series replacements. Matching the carburetor identification number remains important because visually similar Weber marine carburetors can use different calibration parts.
