It is built to OEM quality standards for correct fit, form, and function, so it drops in as a straightforward replacement without modification.\u003c\/p\u003e\u003cp\u003eThe belt is constructed from high-quality polychloroprene rubber reinforced with polyester fiber tensile members, giving it oil resistance and temperature stability for continuous duty in a marine engine bay. This construction resists the heat cycling, oil exposure, and constant flexing that shorten the life of lower-quality belts, helping maintain steady drive tension for the water pump, alternator, and other engine-driven accessories.\u003c\/p\u003e\u003cp\u003eSierra manufactures serpentine belts across a wide range of sizes to match the drive systems used on different MerCruiser engine families, and 18-15103 is the specific part engineered for the 8.2L MPI MIE application referenced above. Confirm your engine model and serial number against the range listed here before ordering to ensure correct fitment.\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 18-15103\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e MerCruiser 8.2L MPI MIE, 1998-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Serial Number Range:\u003c\/strong\u003e OL002450-OL674200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces:\u003c\/strong\u003e 57-865615007\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polyester, Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Style:\u003c\/strong\u003e Serpentine Belt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit Type:\u003c\/strong\u003e Universal Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282145378\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMerCruiser 8.2L MPI MIE, 1998-01, serial number range OL002450-OL674200\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e57-865615007\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engine does Sierra 18-15103 fit?\u003c\/strong\u003e Sierra part 18-15103 is engineered for MerCruiser 8.2L MPI MIE engines within the OL002450-OL674200 serial number range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes 18-15103 replace the OEM belt 57-865615007?\u003c\/strong\u003e Yes, Sierra 18-15103 is a direct replacement for OEM number 57-865615007 on the applicable MerCruiser 8.2L MPI MIE engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the belt made of?\u003c\/strong\u003e The belt is constructed from polychloroprene rubber with polyester fiber tensile members, giving it oil resistance and temperature stability for marine engine use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is this serpentine belt?\u003c\/strong\u003e Sierra 18-15103 is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the belt weigh?\u003c\/strong\u003e Sierra part 18-15103 weighs 0.55 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if this belt fits my MerCruiser?\u003c\/strong\u003e Check your engine's serial number against the OL002450-OL674200 range specified for the 8.2L MPI MIE application; 18-15103 is engineered specifically for that range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or a generic aftermarket belt?\u003c\/strong\u003e This is a genuine Sierra part, number 18-15103, manufactured to OEM quality standards for fit, form, and function.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat comes in the box with 18-15103?\u003c\/strong\u003e The package contains one Sierra serpentine belt, part number 18-15103.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-15103 a serpentine belt or a V-belt?\u003c\/strong\u003e It is a serpentine belt design, part number 18-15103, used on the accessory drive of the specified MerCruiser engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this part?\u003c\/strong\u003e Sierra 18-15103 has UPC 808282145378.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988088008923,"sku":"SIE-18-15103","price":87.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-15103_lg__57460.1558121736.500.750.jpg?v=1785188048","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-15103-serpentine-belt-for-mercruiser-replaces-57-865615007-57-861050-96-75-in-x-13-16-in","provider":"Good Vibes Marina","version":"1.0","type":"link"}
