Sierra 18-7223 Carburetor Kit, Replaces OMC 391305/391937/398452/398453/439070, Johnson/Evinrude 6-9.9 HP Outboards

The Sierra 18-7223 Carburetor Kit is a replacement carburetor rebuild kit built for Johnson/Evinrude (OMC/BRP) outboard motors. It is designed to restore proper carburetor function on small outboards, giving boaters an accurate-fitting alternative to worn or damaged factory components. The kit is manufactured with machined construction for a precise, dependable fit during reinstallation.

This kit is the carburetor kit without float for its application: the float itself is not included, and the matching needle and seat are supplied separately under Sierra part number 18-7094 rather than bundled into 18-7223. It is engineered to cross over directly to a set of factory OMC carburetor part numbers, making it easy to source a correct rebuild kit using either the Sierra number or the equivalent OEM number.

Fitment covers specific Johnson/Evinrude outboard applications: 6 HP model years 1984-85, 7.5 HP model years 1982-83, 8 HP model years 1984-85, and 9.9 HP model years 1974-88. Buyers working on 1986-96 Johnson/Evinrude 6 or 8 HP outboards should note that those model years use a different carburetor kit, Sierra 18-7219, rather than the 18-7223 covered here.
