Mercury / MerCruiser Quicksilver Rotary Actuator — 8M0142768

The Mercury Quicksilver 8M0142768 is a genuine OEM rotary actuator used in the exhaust system control assembly on certain modern Mercury outboard engines. The actuator precisely rotates a valve mechanism to control exhaust flow and optimize engine performance and emissions.


Key Specifications

  • Part Number: 8M0142768

  • Component Type: Rotary actuator

  • OEM Brand: Mercury Marine / Quicksilver

  • UPC: 745061162693

  • Typical MSRP: about $160 USD depending on supplier.


Compatible Engines

This actuator is associated with Mercury V10 outboard engines, including:

  • 350 HP V10 Verado

  • 350 HP V10 SeaPro

  • 400 HP V10 Verado

Typical serial range examples include 3B266064 and newer, depending on the specific model configuration.


Function

The rotary actuator is part of the engine exhaust control system and is responsible for:

  • Rotating the exhaust valve mechanism

  • Managing exhaust flow and pressure

  • Helping optimize engine efficiency, noise control, and emissions

These actuators are electronically controlled by the engine management system to adjust exhaust behavior under different operating conditions.


Signs of a Faulty Actuator

If the rotary actuator fails or sticks, symptoms may include:

  • Engine warning or fault codes

  • Reduced engine performance

  • Abnormal exhaust noise

  • Improper exhaust valve operation

Replacement with the OEM actuator restores proper electronic exhaust control.


āš ļø Fitment Tip:
Always confirm compatibility using the engine model and serial number. Mercury V10 Verado engines use multiple electronic components that may appear similar but are calibrated for specific engine platforms.
