    302537 is an ordinary o-ring. It just sits there, nothing moving. As for a quad ring in the upper seal, OMC didn’t use them there. I don’t know any reason why or why not. Quad ring part number is 305098. marineengine is mighty proud of them. I bought 100 from mcmaster several years ago and have been giving them away ever since.
