This belt drives the water pump and other engine-driven accessories, and it is built to meet or exceed the specifications of the original equipment belt it replaces. The 18-15460 supersedes the earlier Sierra part number 18-15290 and cross-references directly to Mercruiser 57-48120, 57-48120A1, and 57-48120Q1, giving boat owners a reliable direct-fit replacement without hunting for a discontinued OEM number. It also cross-references to OMC 310953 and 909971, Evinrude\/Johnson 909971, Mallory 9-55002, and Volvo Penta 950818 and 829207, making it a useful reference point for cross-brand interchange on comparable belt-driven marine engines. The belt has an effective length of 46 inches and weighs 0.26 pounds. Correct belt selection depends on matching your engine's exact model and serial number range, since Mercruiser and MerCruiser-family engines used several different belt part numbers across model years; the 18-15460 is specific to the 1995-1996 350 MAG MPI\/SKI serial range noted above. Always confirm your engine's serial number before ordering to ensure proper fit.\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 18-15460\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Style:\u003c\/strong\u003e V-Belt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Length:\u003c\/strong\u003e 46 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Fitment:\u003c\/strong\u003e 5.7L 350 MAG MPI \/ 350 MAG SKI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment Years:\u003c\/strong\u003e 1995-1996\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Displacement:\u003c\/strong\u003e 350 cid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinders:\u003c\/strong\u003e 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSerial Number Range:\u003c\/strong\u003e F350583 - F799999\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.26 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999566577\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupersedes Sierra Part Number:\u003c\/strong\u003e 18-15290\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterchangeable With:\u003c\/strong\u003e Mercruiser 57-48120, 57-48120A1, 57-48120Q1;
