As the full flow filter in the engine's lubrication system, it processes all oil circulating to the engine, trapping contaminants with high-efficiency filter media that meets or exceeds original equipment filtration standards. The filter uses a heavy-wall steel canister for structural strength under marine operating pressures, and the canister is epoxy coated for corrosion resistance in the harsh marine environment -- an important detail for engines operating in salt air and bilge moisture.\u003c\/p\u003e\u003cp\u003eThis filter carries an M16 x 1.5 thread and cross-references directly to Volvo Penta OEM part 3582732. It is designed to work with 15W-40 oil meeting VDS-2 or VDS-3 \/ API CI-4 or higher specifications, and pairs with a 12.5 liter (13.2 quart) full oil capacity on the D4 engines it fits. A companion bypass filter (Sierra 18-0036, Volvo Penta 3582733) is used alongside the full flow filter on the same engines to filter a smaller side stream of oil for finer particulate removal -- the 18-0035 is the full flow unit, not the bypass unit.\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 18-0035\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Full Flow Oil Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Epoxy coated, white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e M16 x 1.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.77 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Capacity (D4 Series, Full Flow):\u003c\/strong\u003e 12.5 liters \/ 13.2 quarts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Oil:\u003c\/strong\u003e 15W-40, VDS-2 or VDS-3 \/ API CI-4 or higher\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 3582732\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282290863\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVolvo Penta D4-180iB \/ C \/ D \/ E, 2005 -

Each belt ships as a single unit ready to install using the engine's existing tensioner.\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 18-15115\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e 57-861757, 57-861757Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Style:\u003c\/strong\u003e Serpentine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 13\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 97.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polyester, Rubber\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 808282145491\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eSierra 18-15115 is identified by its own part number for MerCruiser serpentine belt applications; confirm fitment against the OEM numbers below or against part number 18-15115 directly.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e57-861757\u003c\/li\u003e\n\u003cli\u003e57-861757Q\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Sierra 18-15115 serpentine belt?\u003c\/strong\u003e It measures 13\/16 inch wide by 97.5 inches long, the exact dimensions needed for a correct OEM-matching fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does 18-15115 replace?\u003c\/strong\u003e Part number 18-15115 cross-references to OEM numbers 57-861757 and 57-861757Q, so either original belt can be replaced with this one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is this belt made from?\u003c\/strong\u003e The belt is made from polyester and rubber, using polychloroprene rubber combined with polyester fiber tensile members for strength and heat resistance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-15115 belt oil and heat resistant?\u003c\/strong\u003e Yes, oil resistance and temperature stability are standard features of this belt's construction, which suits the engine-bay environment it operates in.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine OEM belt or an aftermarket replacement?\u003c\/strong\u003e The 18-15115 is a Sierra aftermarket belt engineered to OEM quality standards for fit, form, and function, not a manufacturer-branded original part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does 'serpentine belt' mean for this application?\u003c\/strong\u003e A serpentine belt is a single continuous-loop belt, like the Sierra 18-15115, that drives multiple engine accessories from one belt routed around the engine's pulleys.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order part number 18-15115?\u003c\/strong\u003e One serpentine belt, part number 18-15115, ships as a single unit ready to install with the engine's existing tensioner.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this belt fit any engine that uses a 13\/16 by 97.5 inch belt?\u003c\/strong\u003e Sierra 18-15115 is sized 13\/16 inch wide and 97.5 inches long, so it fits engines specified for that belt length and width or for OEM numbers 57-861757 or 57-861757Q.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if I need 18-15115 versus a different Sierra belt number?\u003c\/strong\u003e Match the belt by its length and OEM cross-reference; 18-15115 is 97.5 inches long, while other Sierra part numbers in the same line cover different lengths, so confirm against your original belt's OEM number, 57-861757 or 57-861757Q.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the weight of the 18-15115 belt?\u003c\/strong\u003e The Sierra 18-15115 serpentine belt weighs 0.55 pounds.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988088369371,"sku":"SIE-18-15115","price":89.98,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-15115_lg__65242.1722519132.500.750.jpg?v=1785188825"},{"product_id":"sierra-18-15121-serpentine-belt-replaces-mercruiser-57-865615005-57-863876-5-87-5-in-x-13-16-in","title":"Sierra Serpentine Belt 18-15121 for MerCruiser MX 6.2L MPI MIE, Horizon, Ski Engines","description":"\u003cp\u003eThe Sierra 18-15121 serpentine belt is a direct-fit drive belt engineered for MerCruiser MX 6.2L MPI engines, including MIE, Horizon MIE, and Ski configurations within the applicable serial number ranges.

The kit contains the three fasteners needed for a complete mount attachment: a washer, a lock nut, and a motor mount bolt, so you are not stuck trying to source individual hardware pieces separately when a mount bolt is worn, corroded, or missing. Each piece is made from stainless steel with a machined finish and a hex head style, using 1\/2-13 UNC right hand threading that is fully threaded along its length. Sierra manufactures this kit to meet or exceed the original equipment part it replaces, and it interchanges directly with GLM 21080 and Mercury Marine 10-97934A1, making it a straightforward drop-in replacement for stern drive engine mount service. Because engine mount hardware carries significant load and vibration during operation, using correctly graded, corrosion-resistant fasteners like this kit helps maintain a secure engine mount connection rather than reusing stretched or rusted original hardware.

It features an anti-drain-back valve that keeps oil in the filter between starts, so lubrication reaches critical engine components immediately on startup rather than after a delay. The canister is made of heavy-wall steel with an epoxy coating for corrosion resistance, helping the filter withstand exposure to moisture and salt air over its service life. Inside, a high-efficiency filter media meets or exceeds OE filtration performance, capturing contaminants to help protect engine internals from premature wear. The filter uses a 20mm x 1.5 thread spec and is a universal fit across the Honda outboard applications it cross-references to. It is backed by Sierra's warranty and built from premium-grade materials intended to excel in extreme marine conditions.
