Here is a scarce Mercury antique outboard motor cowl set.  This will fit the 3.6hp single cylinder model KF3.  It may fit the KE3 model as well but would not be correct.  The tiller handle is in a different location on the KE3.  From a clean fresh water organ donor with very low hours.  Outstanding original paint that isn't badly faded. These covers are amazingly hard to find.  Most of the surviving KF3 engines are missing these lower cowls.  If you don't have a KF3 now but want one, you should buy thee cowls.  When you finally find your KF3 it will most likely be missing these covers.   Look at the photos and email with questions.  Thanks for looking.
