Sierra 18-7046 Carburetor Kit, Replaces 432962, for Evinrude/Johnson 125-185 HP Outboards

The Sierra 18-7046 Carburetor Kit is a replacement rebuild kit for Evinrude and Johnson outboard motors, designed to restore carburetor performance on engines that used the original 432962 carburetor kit. This kit does not include a float, so it is intended for carburetors that retain their existing float assembly and only need the wear components refreshed. It covers a range of Evinrude/Johnson outboards from 125 HP up through 185 HP, spanning multiple production years as listed in the fitment chart below, making it a useful reference part for anyone servicing an older Evinrude or Johnson powerhead where the original carburetor kit part number is unknown.

A carburetor kit of this type typically supplies the gaskets, seals, and small components needed to rebuild a carburetor during routine maintenance or after it has developed rough idle, flooding, or hard-starting symptoms caused by worn internals. Installing a fresh kit at the correct interval helps keep the carburetor sealing properly and metering fuel as designed, which supports reliable starting and smooth running. Because it is built to Sierra's quality standard, it is intended to meet or exceed original equipment performance when installed in place of the original OEM kit.
