The prop cone fits over the propeller hub and shaft assembly, streamlining water flow behind the propeller to improve efficiency and reduce drag during operation. As a wear item that is exposed to constant water contact and occasional impact during propeller service, the prop cone should be inspected whenever the propeller is removed for maintenance or replacement.\u003c\/p\u003e\u003cp\u003eThis Sierra prop cone is built as a direct equivalent to the original Volvo Penta parts it replaces, so it installs using the same fit and mounting method as the OEM component. It is sold as a single unit and is intended for stern drive owners performing propeller service, replacing a damaged or corroded cone, or restoring lower unit components to original specification.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-4210\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Prop Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.36 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999317575\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVolvo Penta AQ200\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ250\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ270\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ270T\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ275\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ280\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ280T\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ280PT\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ290\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVOLVO 850785-7\u003c\/li\u003e\n\u003cli\u003e854045-2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-4210 prop cone used for?\u003c\/strong\u003e It is a propeller cone that mounts over the propeller hub on Volvo Penta stern drives, streamlining water flow behind the propeller and covering the shaft during operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich Volvo Penta stern drives does the 18-4210 prop cone fit?\u003c\/strong\u003e The Sierra 18-4210 fits Volvo Penta AQ200, 250, 270, 270T, 275, 280, 280T, 280PT, and 290 stern drives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-4210 replace OEM Volvo Penta part numbers?\u003c\/strong\u003e Yes, the 18-4210 is a direct equivalent for Volvo Penta OEM numbers 850785-7 and 854045-2.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-4210 prop cone weigh?\u003c\/strong\u003e The Sierra 18-4210 prop cone weighs 0.36 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many prop cones come in one order?\u003c\/strong\u003e One order includes a single Sierra 18-4210 prop cone, sold individually.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-4210 a genuine Volvo Penta part or an aftermarket replacement?\u003c\/strong\u003e The 18-4210 is a Sierra-manufactured aftermarket part built to replace Volvo Penta OEM numbers 850785-7 and 854045-2, not a Volvo Penta branded part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should a boat owner replace the prop cone on a Volvo Penta stern drive?\u003c\/strong\u003e The prop cone should be checked and replaced if it is cracked, corroded, or missing whenever the propeller is removed for service on a compatible Volvo Penta stern drive.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs installation of the 18-4210 prop cone straightforward for a DIY boat owner?\u003c\/strong\u003e Yes, since the Sierra 18-4210 is designed to mount using the same fit as the original Volvo Penta prop cone, it installs the same way during routine propeller service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-4210 covered by a warranty?\u003c\/strong\u003e The Sierra 18-4210 prop cone is covered under Sierra's manufacturer warranty against defects.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-4210 prop cone?\u003c\/strong\u003e The UPC for the Sierra 18-4210 prop cone is 030999317575.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988171043035,"sku":"SIE-18-4210","price":78.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-4210_lg__95090.1558125957.500.750.jpg?v=1785188796","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-4210-prop-cone-for-volvo-penta-stern-drive-replaces-oem-850785-854045-fits-aq200-290","provider":"Good Vibes Marina","version":"1.0","type":"link"}
