I did a little research and seems the decals available for the 2002 30HP Johnson engine has the same looks as the ones on your engine. The 2003 version doesn't. So unless someone changed the cowl cover, I'd say you have a 2002 Johnson 30HP engine. Some of the Johnson engines have a welch type looking plug on the top of the engines. If yours has one, copy the numbers down from it and see exactly what you have... JMHO!
