OMC Evinrude Johnson Screw

OMC, Evinrude, and Johnson outboard motors use various screws for different purposes, and they are generally identified by their part number. For example, a screw with the part number 0308684 is a genuine Johnson/Evinrude/OMC screw, and a seller on Amazon says it's an OEM part. Another Screw, 0303764, is also used on vintage Evinrude and Johnson outboard engines.
