{"product_id":"volvo-650","title":"Volvo Penta Exhaust Manifold 3847501","description":"\u003cp\u003eVolvo 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 \u003cstrong\u003eexhaust manifold\u003c\/strong\u003e, and the strongest public fitment trail ties it to \u003cstrong\u003e5.0L and 5.7L\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Volvo Penta OEM exhaust manifold, part number \u003cstrong\u003e3847501\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eIdentified in current Volvo-focused parts sources as an \u003cstrong\u003eexhaust manifold\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eStrong current fitment support centers on \u003cstrong\u003eGM small block 5.0L and 5.7L V8\u003c\/strong\u003e marine engines with \u003cstrong\u003ecenter-riser\u003c\/strong\u003e exhaust layout.\u003c\/li\u003e\n\u003cli\u003eCurrent cross-reference trails associate it with earlier numbers including \u003cstrong\u003e914035\u003c\/strong\u003e, \u003cstrong\u003e913582\u003c\/strong\u003e, \u003cstrong\u003e3852374\u003c\/strong\u003e, and \u003cstrong\u003e3857723\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eOne current public listing shows approximate weight around \u003cstrong\u003e35 lb\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eEngine Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe strongest supportable fitment trail for Volvo Penta 3847501 is with Volvo Penta \u003cstrong\u003e5.0L and 5.7L GM small block V8 gasoline engines\u003c\/strong\u003e using the \u003cstrong\u003ecenter-riser exhaust manifold\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eFitment can vary by engine family, exhaust-riser style, and serial-number range. Confirm Volvo Penta part number \u003cstrong\u003e3847501\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eReplace 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.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eMatch this manifold to the exact Volvo Penta application before installation. Current public references most clearly support \u003cstrong\u003ecenter-riser 5.0L \/ 5.7L small block\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch2\u003eAlternate\/Superseded Part Numbers\u003c\/h2\u003e\n\u003cp\u003eCurrent public cross-reference sources associate Volvo Penta \u003cstrong\u003e3847501\u003c\/strong\u003e with related earlier numbers \u003cstrong\u003e914035\u003c\/strong\u003e, \u003cstrong\u003e913582\u003c\/strong\u003e, \u003cstrong\u003e3852374\u003c\/strong\u003e, and \u003cstrong\u003e3857723\u003c\/strong\u003e, along with aftermarket references such as \u003cstrong\u003eBarr OMC-1-914035\u003c\/strong\u003e and \u003cstrong\u003eOsco 57579 \/ 52374\u003c\/strong\u003e.

On older GM-based Volvo Penta V8s, confirming the exact \u003cstrong\u003ecenter-riser\u003c\/strong\u003e setup first usually saves a lot more time than trying to match a used manifold by shape alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564016336932,"sku":"3847501","price":655.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/50221142-b081-410f-8661-d6be3c80504e.png?v=1776453769","url":"https:\/\/marisolmarine.com\/products\/volvo-650","provider":"Marisol Marine Company","version":"1.0","type":"link"}
