Sierra Marine 181843 Dry Joint Exhaust Manifold

Cast Iron; Gasket Included; Mounting Hardware Included; Fits Mercruiser Stern Drive Engines

The Sierra Marine 181843 Exhaust Manifold is a dry joint replacement component designed for marine engine exhaust systems. Its dry joint configuration separates the exhaust passage from the engine cooling water path at the manifold connection, supporting a clean and serviceable installation when replacing a corresponding original component. This manifold is identified by Sierra Marine part number 181843 and is suited for repair, maintenance, and restoration applications where the correct dry joint exhaust design is required.
Use the Sierra Marine 181843 manifold to help restore the exhaust system to its intended configuration. The exhaust manifold collects gases from the engine cylinders and directs them toward the remaining exhaust components, making it an important part of the overall marine propulsion system. Replacing a worn, damaged, or compromised manifold can help address exhaust system service needs and support proper component
