JustinHoffman Posted April 23, 2007 Report Share Posted April 23, 2007 Hello All, Time to de-winterized the boat, and can't seem to find my owners manual. Does anyone know the appropriate gap space for the spark plugs for a 20HP Johnson from 1988? Thanks in advance! Good Fishing, Justin Link to comment Share on other sites More sharing options...
