MERCURY MARINE SMALL BLOCK
PCM CONVERSION CALIBRATION SERVICE

The Whipple Mercury Marine Small Block PCM Conversion Calibration Service is designed for compatible repower applications where an older 305 MPI or 350 Magnum engine package is being updated to a compatible 350 Magnum, 377, or 383 engine. This calibration service updates the existing PCM with the proper calibration for the new engine combination when the PCM, engine package, and drive configuration are supported.

Whipple has extensive experience with PCM555 calibration development and Mercury Marine small block applications. With full PCM control, Whipple can support many Mercury Marine repower combinations, including Alpha and Bravo style drive configurations, when the complete application details are confirmed before calibration.
