For your consideration is a used exhaust elbow/riser removed from a Mercruiser 165 inline 6. I believe this is an OEM Mercruiser part but it could be aftermarket. I believe this is compatible with a lot of the Mercruiser inline 4 cylinders and even some v8s and v6s, but I leave that up to you to verify.

I was going to keep to this as a a spare but decided against it. Gasket surface needs to be cleaned, but otherwise should be ready to go! I personally like to set these on the ground upside down and pour in some rust remover and let it sit for a few days, but that's just me. 

Ready to install and use. Shipping will be following day after receiving payment. A tracking number will be provided.
