MerCruiser® Throttle Position Sensors

TPS replacements for MerCruiser® EFI and MPI engines. Each product family is referenced by both historical OEM number and current Mercury replacement.

TPS compatibility is engine-generation specific. The earlier EFI/TBI and 454 MAG MPI families use a different TPS than the 7.4L L29, ECM-555, and 496/8.1L families. Do not select by displacement alone.
