Serial Number Fitment Notice
Confirm fitment by Volvo Penta engine model, serial number, and the correct exhaust system parts diagram. Large Volvo Penta diesel engines may use different exhaust gaskets depending on turbocharger arrangement, exhaust elbow configuration, riser style, and production version. Use 863353 only where the diagram specifically calls for this gasket.
When This Part Needs Replacement
Replace this gasket whenever the exhaust elbow or related exhaust flange is removed. It should also be replaced if exhaust soot is visible around the joint, if there is water staining or salt buildup near the mating surface, if the gasket is crushed or burned, or if the exhaust connection has been disturbed during turbocharger, riser, manifold, or wet-exhaust service.
Installation Notes
Clean both mating surfaces before installation and inspect the exhaust elbow, flange, mounting studs, nuts, and surrounding water passages for corrosion or distortion. Do not reuse an old exhaust gasket once the joint has been opened. Follow the Volvo Penta service manual for the correct assembly sequence and torque specification for the specific engine and exhaust configuration.

Parts Desk Insight
Exhaust elbow gaskets on large Volvo Penta diesel engines operate in a high-heat, high-vibration, wet-exhaust environment. A leaking gasket can allow exhaust soot, saltwater residue, or hot gas to escape into the engine space. Matching the gasket by engine serial number and exhaust diagram is important because similar D12 and TAMD exhaust layouts can use different flange gaskets.
