Sierra 18-1992-1 80-Degree Marine Exhaust Elbow Adapter for 3" I.D. Exhaust Hose

The Sierra 18-1992-1 Exhaust Elbow Adapter is an 80-degree cast iron elbow designed to solve challenging marine exhaust routing situations. When an exhaust run requires a sharp turn to route around other engine room components, this adapter provides a clean solution without sacrificing flow volume or performance.

Engineered for use with 3" I.D. exhaust hose, this elbow provides an 80° bend that maintains a constant slope throughout the exhaust run. The geometry of the elbow achieves the required directional change without constricting the interior volume of the hose, helping preserve proper exhaust flow and backpressure characteristics.

Key Features:

• 80-degree bend for sharp exhaust routing changes
• Designed for use with 3" I.D. marine exhaust hose
• Compatible with the 18-1987 Exhaust Manifold Conversion Kit
• Replaces Barr part number 200087P
• Includes four stainless steel hose clamps for a complete, out-of-the-box installation
• Meets or exceeds OEM specifications

The Sierra 18-1992-1 is a direct replacement for Barr 200087P and is built to Sierra's standard of meeting or exceeding the original equipment part it replaces. Four stainless steel hose clamps are included, making this a complete installation-ready solution for inboard marine exhaust systems.
