This is an exhaust elbow to connect the exhaust manifold to the Y pipe. I have both sides, don't know which one is which. This one has the same 6 digit number stamped in it as the other one but with a number 2 under it by itself. The other one has a 1. Comes with rubber boots and clamps pictured.
I have the 4 winns boat and engine and have many unlisted good parts.
The casting number on the engine block comes back as a 1992 year engine. I will add that to the pictures
