Exhaust kit for a Mercruiser small block V8 engine with a 3" exhaust outlet. This kit includes the manifolds and risers along with the gaskets and mounting kits necessary for installation. The parts in this kit are made from cast iron and are electro deposition coated for corrosion resistance.

NOTE: If your engine is equipped with the dry joint exhaust system (V8 serial #0m600000 and above), THIS IS THE WRONG MANIFOLD; you must purchase the Mercruiser OEM manifold.
