Product Details

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.

Key Features:

  • Genuine OEM Quicksilver / Mercury Marine replacement part
  • Functions as the Electronic Spark Control (ESC) / knock control module
  • Monitors knock sensor output and regulates ICM signal for timing protection
  • Helps maintain optimal engine timing under varying load and fuel conditions
  • Direct OEM replacement — engineered to Mercury Marine specifications
  • Part of the trusted Quicksilver line of Mercury Marine original equipment parts and accessories

Always pair this ESC module with the correct knock sensor for proper system performance. Refer to your MerCruiser service manual for specific application guidance and installation instructions.

Good overall

The screw driver pops out of the slot making adjustment difficult

Quick and easy no annoying pop ups or sales ads

Product was as described

Because of the SOARING fuel prices (Putin? No...), I needed to buy a locking gas cap. It got here quick, fit and works perfect! My truck has a 32 gallon fuel tank so to lose THAT much fuel to one of our local miscreants just seems unacceptable. I'm actually SAVING someone from becoming a criminal!

It was easy to navigate and not complicated, and straight forward.
