Sierra 18-15480 V-Belt for MerCruiser 8.2L MIE and 8.2L MPI MIE 502 Engines, White
Sierra 18-15480 V-Belt for MerCruiser 8.2L MIE and 8.2L MPI MIE 502 Engines, White
The Sierra 18-15480 is a white V-belt engineered for MerCruiser 8.2L MIE and 8.2L MPI MIE stern drive engines with the 502 cid, 8-cylinder, 4-barrel configuration. This belt drives engine accessories off the crankshaft pulley and is built to meet or exceed the original equipment part it replaces, so it holds up to the heat, oil exposure, and constant flexing found in a marine engine bay.
Fitment is tied to specific engine serial number ranges across several production runs of the 8.2L MIE and 8.2L MPI MIE, so buyers should confirm their engine's serial number falls within the ranges listed below before ordering. The belt is also cross-referenced to common Mallory and Mercruiser part numbers, making it a straightforward swap for boaters replacing a worn OEM belt or working from an existing cross-reference number.
