This white, round seal is built to meet or exceed original equipment quality, giving boat owners a reliable replacement for maintaining a proper seal against oil leakage in the stern drive assembly. Sierra manufactures its seals to close tolerances so fit and sealing performance match what the stern drive was originally designed for, helping prevent oil loss and water intrusion that can damage internal drive components over time.\u003c\/p\u003e\u003cp\u003eThis seal cross-references directly to the OEM Volvo part number, making it a straightforward like-for-like replacement for boaters servicing their stern drive as part of routine maintenance or a leak repair. Its compact, lightweight design (0.01 pounds) reflects its role as a precision sealing component rather than a structural part, and it is intended to be installed exactly where the original OEM seal was located.\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 18-2045\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Oil Seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Volvo Penta Stern Drive\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eVolvo Penta stern drive\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVolvo 827247-8\u003c\/li\u003e\n\u003cli\u003eGLM 70640\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 0581419\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 0580422\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-2045 used for?\u003c\/strong\u003e The Sierra 18-2045 is an oil seal designed for Volvo Penta stern drive units, sealing the drive to prevent oil leakage and water intrusion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this seal fit Volvo Penta stern drives only?\u003c\/strong\u003e Yes, the 18-2045 oil seal is designed specifically for Volvo Penta stern drive applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-2045 replace?\u003c\/strong\u003e It replaces Volvo OEM part number 827247-8, along with GLM 70640 and Evinrude\/Johnson 0581419 and 0580422.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2045 a genuine Volvo part or aftermarket?\u003c\/strong\u003e The 18-2045 is a Sierra aftermarket seal manufactured to meet or exceed original equipment quality, not a genuine Volvo-branded part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-2045 oil seal?\u003c\/strong\u003e The Sierra 18-2045 oil seal is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is the Sierra 18-2045 seal?\u003c\/strong\u003e It is round in shape, consistent with standard stern drive oil seal designs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-2045 weigh?\u003c\/strong\u003e The 18-2045 oil seal weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-2045 be used to fix an oil leak in a stern drive?\u003c\/strong\u003e Yes, replacing a worn seal with the Sierra 18-2045 is a common way to resolve an oil leak in a Volvo Penta stern drive.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Evinrude\/Johnson 0581419 seal the same as the Sierra 18-2045?\u003c\/strong\u003e The Sierra 18-2045 is interchangeable with Evinrude\/Johnson 0581419 and 0580422, meaning it can be used as a direct replacement for those numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the Sierra 18-2045?\u003c\/strong\u003e The order includes one Sierra 18-2045 oil seal for Volvo Penta stern drive applications.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988090728667,"sku":"SIE-18-2045","price":13.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-2045__70493.1722512845.500.750.jpg?v=1785188854","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2045-oil-seal-volvo-penta-833996-12-x-24-x-7-mm-stern-drive-seal","provider":"Good Vibes Marina","version":"1.0","type":"link"}
