I just got a used Yamaha 9.9, but can not determine the year model. There is no data plate. It is white with a square-ish head. 4 stroke, electric start, long shaft, equipped with a dual purpose prop (High Thrust??). "6G3-00", "6G3-02", and other "6G3" characters appear inside the engine at various places. Does anyone know what year this could be so I can get an owner's manual from Yamaha?
