The Sierra 18-1976-2 Manifold Elbow is a 4 inch hose, 7 degree down angle exhaust manifold elbow built to fit the 18-1953-2 exhaust manifold. It directs exhaust flow from the manifold to the connected exhaust hose at the correct angle for proper drainage and reliable engine cooling water discharge, replacing worn or corroded factory elbows that can leak exhaust or coolant.

This elbow is a direct cross-reference for Mercury Marine 44354A3 and 807914A1, so it installs as a like-for-like replacement without modification. It is finished in black and is designed to pair with the correct elbow gasket for a sealed connection at the manifold. Sierra recommends using elbow gasket 18-2849-1 or 18-0897 with this elbow, and the matching 18-8505 mounting kit (sold separately) includes an 18-0897 elbow gasket specifically for use with this riser.

Each unit ships as a single elbow (1 pack), intended for engine and drive system repair and maintenance work where the original manifold elbow has failed or is due for preventive replacement.
