The Sierra 18-0993 is a cover and gasket assembly that replaces Johnson/Evinrude part 437228. It is meant for Johnson and Evinrude engines fitted with a primer valve. There are exclusions: it does not cover 1993 engines or the 9.9 and 15 hp models. Check your engine against those before relying on it.
Our take
The primer valve condition on Sierra 18-0993 is the first thing to check, since it is meant for Johnson/Evinrude engines with one. The 1993 year and the 9.9 and 15 hp models are excluded, so those owners need another part.
