Sierra Carburetor Kit 18-7042, Replaces OMC 392061, 396701, 398729

The Sierra 18-7042 Carburetor Kit is a gasoline-application rebuild kit designed to restore carburetor performance on applicable outboard engines. This kit is built to replace worn or degraded internal carburetor components, helping resolve common issues such as rough idle, poor fuel atomization, and inconsistent throttle response caused by aged gaskets, seals, and other wear parts inside the carburetor body. The kit carries a machined exterior finish and is packaged as a single complete unit (1 count) to simplify ordering for a single carburetor rebuild.

Sierra sources this kit as a direct cross-reference to OMC carburetor part numbers 392061, 396701, and 398729, making it a straightforward replacement option for boat owners and marine technicians working on engines that originally used those OMC carburetor assemblies. The kit is backed by a limited warranty and is intended for gasoline fuel systems only.
