It is built to transfer power reliably between the crankshaft pulley and accessory components such as the water pump, alternator, or power steering pump on applicable engine applications. The belt is finished in black and is supplied as a single unit (1 count).\u003c\/p\u003e\u003cp\u003eThis V-Belt is engineered as a direct cross-reference replacement for the Mercury Marine 57-32850 and 57-69143T belts as well as the OMC 311606 belt, allowing owners to source a compatible replacement without needing the original manufacturer part number. It fits specific serial-number ranges across three 502 CID engine applications: the 8.2L 600 SC (1992-2000), the 8.2L MIE (1993-1997), and the 8.2L MPI MIE (1996-1997). Confirming the engine serial number against these ranges before ordering ensures the correct belt is installed.\u003c\/p\u003e\u003cp\u003eSierra manufactures this belt for straightforward removal-and-replacement service, making it a practical stocking item for scheduled maintenance or belt failure repairs on these MerCruiser-family 502 CID engines.\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 18-15400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e V-Belt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Style:\u003c\/strong\u003e V-Belt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.19 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Displacement:\u003c\/strong\u003e 502 CID\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinders:\u003c\/strong\u003e 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 57-32850, 57-69143T, 311606\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Serial Range, 8.2L 600 SC:\u003c\/strong\u003e D725676 -
