Current public references place it in \u003cstrong\u003eDP-G \/ Marine Propulsion\u003c\/strong\u003e and \u003cstrong\u003eSX-M Upper Vertical Shaft\u003c\/strong\u003e assemblies, while broader public fitment coverage also associates it with many Volvo Penta drive families and older diesel and gasoline applications. Because this nut is part of a thickness-selected upper gear stack-up, the safest fitment standard is the exact Volvo Penta serial-number-based parts diagram for the drive or engine being serviced.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eFitment can vary by drive family, upper gear version, and required stack-up thickness. Confirm Volvo Penta part number \u003cstrong\u003e3852301\u003c\/strong\u003e against the exact serial number and the correct Volvo Penta parts diagram before ordering, especially on upper vertical shaft and upper gear assemblies where nearby nut variants such as \u003cstrong\u003e3852302\u003c\/strong\u003e and \u003cstrong\u003e3852303\u003c\/strong\u003e can look identical but differ by thickness.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eReplace this nut when the original fastener is thread-damaged, rounded, corroded, distorted, or no longer securing the upper gear or shaft assembly correctly. It is also a smart replacement during upper gear or shaft service when the original nut has already been removed and the driveline stack-up is being checked or rebuilt.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eMatch this nut to the exact Volvo Penta application before installation. The strongest public reference places it in the \u003cstrong\u003eupper gear \/ upper vertical shaft\u003c\/strong\u003e group, so confirming both the part number and exact diagram location is the safest cross-check before ordering or reassembly. Because current public references also show thickness-specific variants in this nut family, verifying the required thickness in the parts diagram matters more than matching by thread alone.\u003c\/p\u003e\n\u003ch2\u003eAlternate\/Superseded Part Numbers\u003c\/h2\u003e\n\u003cp\u003eCurrent public Volvo Penta parts references show \u003cstrong\u003e854228\u003c\/strong\u003e and \u003cstrong\u003e839332\u003c\/strong\u003e as earlier numbers updated to \u003cstrong\u003e3852301\u003c\/strong\u003e. Use \u003cstrong\u003e3852301\u003c\/strong\u003e as the current primary OEM ordering number for this listing.\u003c\/p\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eThis is the kind of hardware part that looks generic once it is off the drive, but in upper gear assemblies the wrong thickness can affect the whole stack-up. Matching the exact Volvo Penta diagram position first is usually much safer than substituting by thread and wrench size 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":43564018237476,"sku":"3852301","price":21.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/d76263f3-d80c-4233-a631-4de36d83a299.png?v=1776455020","url":"https:\/\/marisolmarine.com\/products\/volvo-695","provider":"Marisol Marine Company","version":"1.0","type":"link"}
