I have a Mariner 5, 2-stroke, air cooled motor without an id tag. The local Mercury dealer said it was a Yamaha engine. Based on the diagrams I have found on the net I think it is a 661-????? serial number. I am trying to find out what year this motor is so I can buy a manual. I have followed all the links I could find on this site to identify it with no luck. Even used the search function. Also does anybody know what the point gap setting should be?
Thanks
Paul
