Volvo Penta 3847501 is a genuine OEM exhaust manifold used on Volvo Penta GM-based small block V8 marine engines. Current parts references consistently identify this number as an exhaust manifold, and the strongest public fitment trail ties it to 5.0L and 5.7L center-riser gasoline applications. Current cross-reference sources also show this manifold replacing earlier Volvo Penta and OMC numbers in the same center-riser exhaust family.

Engine Compatibility
The strongest supportable fitment trail for Volvo Penta 3847501 is with Volvo Penta 5.0L and 5.7L GM small block V8 gasoline engines using the center-riser exhaust manifold setup. Current public fitment sources list broad coverage across many 5.0GL, 5.0Gi, 5.0GXi, 5.0OSi, 5.7GL, 5.7Gi, 5.7GXi, and 5.7OSXi variants. Because manifold fitment can still vary by riser style and production range, the safest fitment standard is the exact Volvo Penta serial-number-based parts lookup for the engine being serviced.
Serial Number Fitment Notice
Fitment can vary by engine family, exhaust-riser style, and serial-number range. Confirm Volvo Penta part number 3847501 against your engine serial number and the correct Volvo Penta exhaust diagram before ordering, especially on 5.0L and 5.7L applications where center-riser and other manifold styles can look close but are not interchangeable.
When This Part Needs Replacement
Replace this exhaust manifold when the original manifold is cracked, leaking, internally corroded, warped at the sealing surface, or showing signs of exhaust or cooling-water failure. It is also a smart replacement when exhaust-riser service reveals manifold deterioration or when repeated manifold gasket issues point to a damaged casting. This guidance is based on the part type and its exhaust-system role.
Installation Notes
Match this manifold to the exact Volvo Penta application before installation. Current public references most clearly support center-riser 5.0L / 5.7L small block use, so confirming both the part number and the exact exhaust layout is the safest cross-check before ordering or reassembly. One current product source notes it includes a drain plug assembly and 90-degree hose connector, while another notes gaskets are not included, so checking the rest of the exhaust hardware before the job starts is worthwhile.
Alternate/Superseded Part Numbers
Current public cross-reference sources associate Volvo Penta 3847501 with related earlier numbers 914035, 913582, 3852374, and 3857723, along with aftermarket references such as Barr OMC-1-914035 and Osco 57579 / 52374. Use 3847501 as the primary Volvo Penta ordering number for this listing.
Parts Desk Insight
Exhaust manifolds are one of those parts where the engine family alone is not enough. On older GM-based Volvo Penta V8s, confirming the exact center-riser setup first usually saves a lot more time than trying to match a used manifold by shape alone.
