Engineered Marine Products Exhaust Center Riser Elbow, Replaces 44354A3 807914A1, Fits V6/V8 Manifold 18-1953-2, 4 Inch Hose 7 Degree

This Engineered Marine Products exhaust center riser elbow is a manifold elbow designed for V6 and V8 marine engine exhaust systems. It connects to a 4 inch exhaust hose and is built with a 7 degree down angle to route exhaust gas and cooling water away from the manifold and out through the riser hose. The elbow has a machined exterior finish for a precise fit at the hose and manifold connection points.

This riser elbow fits Manifold 18-1953-2 and is compatible with elbow gaskets 18-2849-1 and 18-0897 for sealing the elbow-to-manifold connection. It directly replaces OEM numbers 44354A3 and 807914A1, making it a straightforward swap for boat owners rebuilding or upgrading their exhaust manifold system. As a wear and corrosion-prone component in the exhaust and cooling path, the riser elbow is a common replacement item during routine manifold maintenance or when addressing exhaust leaks and water intrusion.
