More about this item

Mercury Marine 891663001 Sensors

Temperature monitoring is one of the most important functions in any marine engine management system, and the sensor doing that job needs to be accurate. The Mercury Marine 891663001 Temperature Sensor Assembly is a genuine OEM replacement that restores precise temperature monitoring to compatible Mercury engines, giving the engine management system the accurate data it needs to protect the engine and alert you when something is not right.

The temperature sensor assembly monitors engine temperature in real time and feeds that data to the engine control module and gauge system. On Mercury engines integrated with SmartCraft, that data drives both the temperature gauge at the helm and the engine protection system that can reduce power or shut the engine down if temperatures climb into dangerous territory. A sensor that has drifted out of calibration or failed entirely can produce false readings that trigger unnecessary warnings, suppress warnings that should be active, or cause the engine management system to make incorrect decisions about engine protection. None of those outcomes are acceptable on an engine you depend on.

As a genuine Mercury Marine OEM assembly, the 891663001 is calibrated to the exact temperature response curve Mercury specifies for compatible engines. The connector, sealing, and thread specifications match the original, so it installs correctly and communicates accurately with the engine control module from the first start. Aftermarket temperature sensors may fit the port, but calibration differences are common and can compromise the accuracy of everything the sensor feeds.

Key Features:

  • Genuine Mercury Marine OEM temperature sensor assembly
  • Part Number: 891663001
  • Monitors engine temperature for compatible Mercury engine management systems
  • Compatible with Mercury SmartCraft gauge and engine protection systems
  • OEM calibration, connector, sealing, and thread specifications
  • Direct replacement with no modification required

Confirm your engine model and serial number before ordering. Mercury temperature sensor assemblies are application-specific, and verifying the correct part number for your engine ensures accurate calibration and proper integration with your gauge and engine protection system.
