How to Match This Part

This aftermarket temperature sensor assembly replaces Mercury / Mariner / MerCruiser / Quicksilver 885342002 (covers earlier 885342001 and current superseding number 8M0148668). It is a threaded probe-style sensor used on listed Mercury and Mariner EFI, DFI, and Verado outboards, plus listed MerCruiser sterndrive and inboard applications.

Match this part in this order:
1. Number on the sensor you remove — 885342002, 885342001, or 8M0148668
2. Engine family — EFI / DFI / Verado outboard groups or listed MerCruiser MPI / MAG / inboard applications in the compatibility table
3. Serial number on the engine ID plate against the serial notes, then compare the threaded brass probe, hex body, sleeved pigtail, and two-pin blue-lock connector with the product images

Mercury lists 8M0148668 as the current functional replacement for 885342002; the replacement may look slightly different while remaining the correct supersession. Do not order by horsepower alone when a serial-number range is listed.

Part Number Cross-Reference

Use these verified Mercury numbers to confirm you have the correct temperature sensor. Brand names and OEM numbers are for identification only.

Type Brand Part Number Notes
OEM Mercury / Mariner / MerCruiser / Quicksilver 885342002 Primary listing number; SENSOR ASSY-TEMP
OEM Mercury / Mariner / MerCruiser / Quicksilver 885342001 Earlier number in the same supersession chain
OEM Mercury / Mariner / MerCruiser / Quicksilver 8M0148668 Current superseding functional replacement

This is an aftermarket part manufactured by JLM Marine. It is not sold as a genuine Mercury Marine, Mariner, MerCruiser, or Quicksilver component.

Compatible Engine Models

Confirm your engine model and serial number before ordering. For Mercury / Mariner outboards, use the Mercury Serial Number Guide and Mercury Parts Diagrams. For MerCruiser, use the engine identification plate on the engine — not an outboard transom-bracket location.

Installation Guide

  1. 1Confirm the stamped number on the sensor you remove is 885342002, 885342001, or 8M0148668, and that your engine/serial appears in the compatibility table.
  2. 2Disconnect the battery negative cable and allow the engine to cool before opening the cowling or engine compartment.
  3. 3Release the blue connector locks and unplug the sensor by the connector housing. Do not pull on the wires.
  4. 4Place an absorbent cloth below the sensor, remove the old unit with the correct wrench on the hex body, and keep debris out of the threaded opening.
  5. 5Start the replacement by hand to prevent cross-threading, then tighten to the torque in your Mercury / MerCruiser service manual for that engine.
  6. 6Reconnect the plug until it locks, reconnect the battery, then run the engine per the service procedure while checking for leakage, warning messages, and a normal temperature reading.

Note: Professional installation is recommended for temperature sensors on EFI, DFI, Verado, and MerCruiser powerplants.

Troubleshooting & FAQ

How do I confirm this fits my engine? +

Start with the number on the sensor you remove. If it reads 885342002, 885342001, or 8M0148668, match your engine family and serial to the compatibility table and the OEM temperature-sensor diagram before ordering.

Does this replace 885342001 and 8M0148668 as well? +

Yes. 885342001 is an earlier number in the chain; 8M0148668 is the current Mercury functional replacement for 885342002. Confirm the engine model and serial as well as the stamped number.

Why might the replacement look slightly different? +

Mercury superseded 885342002 with 8M0148668 as a functional replacement that may look different. Compare part numbers plus the threaded probe, hex body, sleeved lead, and blue-lock connector — not appearance alone.

Is this an OEM or aftermarket part? +

This is an aftermarket replacement manufactured by JLM Marine. It is not a genuine Mercury Marine, Mariner, MerCruiser, or Quicksilver part. OEM numbers are listed only for cross-matching.

Important Notes

  • Verify the OEM number on your original sensor and your engine serial against the compatibility table before ordering.
  • Confirm thread engagement and connector lock after installation; check for leaks and correct temperature readings on first run.
