I have a 1978 Watkins 27 with a Yanmar YSM 8G. Looking on line I've found the exhaust elbow but I'm not sure if its the correct one. I have a part number if someone here has a parts manual that could look up the part number for me. That way I can cross reference to make sure I order the correct one.
Part Number: 128270-13600 U- Type
