Same as Exhaust Elbow?
My 5411 is rusting out right where the cooling water is mixed with the exhaust. I think that may be the same part (manifold?) you are looking for. I just requested that part from my local dealer & will let you know when I hear how much.P.S. It seemed my raw cooling water was siphoning out through this corrosion caused opening. Make shure to close your through hull!
