Sierra 18-15460 V-Belt for Mercruiser 5.7L 350 MAG MPI/SKI 1995-1996, Replaces 57-48120A1

The Sierra 18-15460 is a V-belt engineered for Mercruiser 5.7L 350 MAG MPI and 350 MAG SKI stern drive engines built in 1995-1996, covering serial numbers F350583 through F799999. 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.
