Hello folks!!
I am trying to figure out the year of this Yamaha 440 engine. It could be an 86 or 87. It runs well but I want to be more exact. Its a y exhaust sing pipe single carb as pictured. the serial number on it is SA437027318. Is there any rhyme or reason to this number to identify this engine? If not can anyone tell me how I can identify the year of it. Thanks much
