Quicksilver 808014T ESC Electronic Spark Control Module for MerCruiser

The Quicksilver 808014T ESC Module is a genuine OEM Electronic Spark Control (ESC) module designed for MerCruiser sterndrive and inboard marine engines. Also known as a knock control module, this component plays a critical role in protecting engine health by monitoring knock sensor signals and adjusting ignition timing accordingly.

The ESC module continuously reads the AC voltage signal from the knock sensor and communicates with the Ignition Control Module (ICM). When no knock is detected, it supplies a steady 8–10 volt signal to the ICM, enabling optimized ignition timing. If engine knock is detected, the module removes that signal, prompting the ICM to retard timing to a safe level and prevent engine damage.
