How to Match This Part

This aftermarket air temperature sensor replaces Mercury / Mariner / Quicksilver 891663001 (and the earlier number 891663). It is a probe-style intake-system temperature sensor used on supported Mercury and Mariner four-stroke outboards and listed Mercury Racing engines.

Match this part in this order:
1. Number on the sensor you remove — 891663001 or 891663
2. Engine family — Verado, EFI FourStroke / Jet, 150 FourStroke, or listed Mercury Racing models in the compatibility table
3. Serial number on the engine ID plate / midsection bracket against the serial notes, then compare the two-hole flange, probe tip, and molded connector with the product images

Depending on the engine, this sensor mounts in the intake manifold, charge-cooler / intake assembly, or integrated air-fuel module. 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 / Quicksilver 891663001 Current temperature sensor assembly
OEM Mercury / Mariner 891663 Earlier number; superseded by 891663001

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

Compatible Engine Models

Confirm your engine model and serial number on the mounting bracket or cowling identification plate. Use the Mercury Serial Number Guide and Mercury Parts Diagrams to verify the temperature-sensor callout on your diagram.

Brand Engine Family Rated HP / Models Serial / Notes
Mercury / Mariner EFI / Jet FourStroke 65 Jet; 75, 80, 90, 100, 115 EFI; 80 Jet Covered OEM where-used blocks include 0P459572 / 1B366823 ranges through 2B094995 and 2B095049 & Up — confirm serial on the IAFM diagram
Mercury 150 FourStroke 150 1B905505 & Up
Mercury / Mariner Verado 4-cylinder 4-stroke 135, 150, 175, 200 Covered OEM where-used blocks include 0P419487 family ranges and 1B227000 / 1B517159 & Up — confirm serial

Mercury Racing Verado / SCi / QC4V (sterndrive & related) 350SCi Verado; 565 EFI; 600 / 662 / 700 / 850 / 1025 / 1075 / 1200 SCi; 1100 / 1350 / 1650 QC4V OEM where-used lists model-specific serial blocks (e.g. 350SCi 1B716557–2B143542; SCi groups from 0M952908 / 0M962886 & Up) — confirm on the racing parts diagram

Always match the number stamped on the sensor you remove. Engines outside these where-used groups use different temperature-sensor part numbers.

Technical Specifications

Specification Value
Part type Air / intake temperature sensor assembly
Primary OEM number replaced 891663001
Earlier number covered 891663
Application Intake-system air temperature sensing (manifold / charge cooler / IAFM as equipped)
Mounting form Two-hole flange with probe-style sensing tip
Seal Fitted O-ring at probe base (as shown on product images)
Connector Integral molded connector housing

Installation Guide

  1. 1Turn the ignition off and disconnect the negative battery cable before opening the cowling or unplugging intake sensors.
  2. 2Locate the temperature sensor on the intake manifold, charge-cooler assembly, or integrated air-fuel module per your engine’s parts diagram. Note connector orientation before unplugging.
  3. 3Remove the flange fasteners and withdraw the old sensor. Compare the new unit side by side — two-hole flange, probe tip, O-ring, and molded connector should match.
  4. 4Confirm the O-ring is seated on the probe, insert the new sensor, and tighten the flange fasteners to the torque values in your Mercury / Mariner service manual.
  5. 5Mate the connector until it latches, route the harness clear of moving parts and heat sources, and reconnect the battery.
  6. 6Start the engine and confirm there are no intake air leaks at the sensor boss and no temperature-related warning codes after a warm-up cycle.

Note: Professional installation is recommended for intake temperature sensors on EFI and Verado engines.

Troubleshooting & FAQ

How do I confirm this fits my engine? +

Start with the number on the sensor you remove. If it reads 891663001 or 891663, match your engine family and serial to the compatibility table and the OEM intake / IAFM parts diagram before ordering.

Does this replace both 891663 and 891663001? +

Yes. 891663001 is the current OEM number; 891663 is the earlier number it supersedes. Either stamp on a removed sensor points to this replacement family when the engine fitment also matches.

Is this a coolant temperature sender? +

No. This listing is an intake-system air temperature sensor assembly for the applications above — not a block-mounted coolant temperature sender or alarm switch used on other Mercury / Mariner engines.

Is this an OEM or aftermarket part? +

This is an aftermarket replacement manufactured by JLM Marine. It is not a genuine Mercury Marine, Mariner, 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 O-ring seating and flange seal to avoid unmetered intake air leaks after installation.
  • This is an aftermarket replacement and is not a genuine Mercury Marine / Mariner / Quicksilver OEM component.
  • Professional installation is recommended for EFI and Verado intake temperature sensors.

Why Choose JLM MARINE?

  • Precision Fit: Cross-referenced to Mercury 891663001 (and superseded 891663) for the Verado, EFI FourStroke, and Racing applications listed above.
  • Quality Control: Each batch is inspected for dimensional consistency and workmanship.
  • Direct from Manufacturer: Aftermarket marine temperature sensors engineered for reliable intake-air temperature feedback.
