Need to replace the exhaust riser on your MerCruiser?

This is a cast iron exhaust manifold riser elbow that fits a wide range of MerCruiser V8 engines, including the 4.3, 5.0, 5.7, 6.2, and 7.4 liters (think 305 and 350).

It's a \wet joint\ style riser with a 4-inch O.D.

Important note: This is NOT for the newer \dry joint\ risers, so make sure you have the older style.
It replaces OEM numbers like 807914, 807988, and 807988Q03.
