Volvo Penta 857618 is a genuine gasket used in the exhaust elbow / riser connection on older Volvo Penta V6 and V8 marine engine applications. Current references identify this part as the gasket for earlier-style exhaust systems with a 3-3/4" exhaust outlet, commonly associated with AQ200, AQ225, AQ260, AQ271, AQ290, and AQ311-series applications.

Engine Compatibility
Current references show Volvo Penta 857618 associated with older-style Volvo Penta V6 and V8 exhaust applications, including AQ200, AQ225, AQ260, AQ271, AQ290, and AQ311 series, along with related earlier exhaust configurations using the 3-3/4" outlet pattern. Additional listings also associate this gasket with certain BB231A and BB261A applications. Fitment should be confirmed by exact engine model, exhaust outlet style, and serial number before ordering.
Serial Number Fitment Notice
Volvo Penta exhaust gaskets can vary by engine family, manifold style, elbow design, and production range. Confirm fitment by engine or drive serial number and by matching the exhaust connection style before ordering. Volvo Penta's current parts shop identifies 857618 as an active genuine gasket listing.
When This Part Needs Replacement
Replace this gasket whenever the exhaust elbow or riser is removed, or when there are signs of sealing failure such as exhaust leakage, water seepage at the joint, carbon tracking, or visible gasket deterioration during service. Because this gasket seals a critical exhaust connection, replacement during manifold or riser service is standard good practice.
Installation Notes
Install on clean, flat mating surfaces and confirm the gasket matches the older-style exhaust outlet pattern before assembly. Inspect the manifold and elbow / riser faces for corrosion, pitting, or warping, since surface damage can prevent a reliable seal even with a new gasket. Torque hardware evenly to the correct specification for the engine application being serviced. The gasket is sold as a single service part in Volvo Penta references, so check quantity needed for the engine being repaired.
Alternate/Superseded Part Numbers
Current cross-reference sources show Volvo Penta 857618 commonly cross-referenced with 835908 and 856039 in the same exhaust gasket family. Some aftermarket references also cross-reference Quicksilver 803356. No confirmed Volvo Penta supersession is currently shown in the reviewed references beyond those commonly referenced replacements and cross-stocks.
Parts Desk Insight
On older Volvo Penta exhaust systems, gasket selection is often less about engine displacement alone and more about the exact manifold-to-riser connection pattern. For this part, the older-style 3-3/4" exhaust outlet detail is one of the most useful checkpoints. Matching by serial number and exhaust joint style helps avoid ordering a gasket that looks close but seals the wrong connection.
