SIERRA Weber/Carter 4-Barrel Carburetor Rebuild Kit – 18-7748

Description

SIERRA Weber/Carter 4-Barrel Carburetor Rebuild Kit – 18-7748 is a carburetor overhaul kit for specified Weber/Carter four-barrel marine carburetors used on MerCruiser 5.7L, 7.4L and 8.2L performance applications. It is designed around the marine 9665/9781-family carburetors and related Carter/Weber numbers.

The kit is appropriate when a compatible carburetor needs internal gasket, seal and fuel-metering service. Because MerCruiser used several similar four-barrel calibrations, match the stamped carburetor number or OEM kit number before ordering.
