Hi <br />I have an Evinrude Lightwin 3 Hp # 3012-15590. I am not sure if it is a 1953 or 1954. I need a new gasket crank case gasket. I think that is what it is called. It goes between the top of the arm casing and the engine where the water is pumped into the cylinder head and the exhust comes out. Any ideas where I can get one and the part number. Thanks I appreciate all the help. It is all gunked up in side here and the gasket is broken.
