The Sierra Marine 180680 Exhaust Manifold Gasket is a replacement sealing component designed for use in compatible marine exhaust manifold applications. Installed between the exhaust manifold and its mating surface, the gasket helps create a properly sealed connection and supports reliable exhaust system performance. It is intended for maintenance, repair, and restoration projects where the original gasket requires replacement.
Use the Sierra Marine 180680 gasket when servicing an exhaust manifold or correcting a worn, damaged, or removed sealing interface. A properly fitted manifold gasket helps reduce the risk of exhaust leakage at the connection point and supports the correct operation of related exhaust components. Before installation, remove old gasket material and inspect the mating surfaces for corrosion, warping, debris, or other conditions that could affect sealing.
This Sierra Marine replacement part is identified by part number 180680 for application reference and ordering accuracy. Confirm compatibility with the engine, manifold, model, and manufacturer service information before purchase or installation. Follow the equipment manufacturer’s recommended installation procedure, including any required fastener sequence, torque specifications, sealant instructions, and post-installation inspection. The gasket should be replaced whenever the manifold is removed if the original sealing component cannot be reused. Sierra Marine 180680 provides a practical replacement option for maintaining a properly sealed marine exhaust manifold assembly.

Features:

  • Replacement exhaust manifold gasket for compatible marine applications
  • Helps seal the connection between the exhaust manifold and mating surface
  • Suitable for maintenance, repair, and restoration work
  • Sierra Marine part number 180680 for application identification
  • Designed for replacement when the original manifold gasket is worn, damaged, or removed
