Sierra 18-7076 Carburetor Kit for Rochester 2BBL, Mercruiser 470 and 485 Stern Drives

The Sierra 18-7076 Carburetor Kit is a rebuild kit designed for the Rochester 2BBL carburetor used on Mercruiser 470 (1976-1984) stern drives and Mercruiser 485 (1980-1982) stern drives. It comes as one carburetor kit per package and is built to restore proper carburetor function on engines where the original gaskets, seals, and internal components have worn out or dried from age and fuel exposure. The kit uses a bolt-on flange type and is intended for gasoline fuel systems.

Sierra manufactures its carburetor kits to meet or exceed the performance of the original equipment part being replaced, giving boat owners a dependable option for carburetor rebuilds without sourcing a full new carburetor assembly. The 18-7076 is cross-referenced to several OEM and aftermarket part numbers, making it straightforward to match against an existing carburetor tag or an old kit box when confirming the correct replacement. This kit is backed by Sierra's standard limited warranty.
