You can trust used Mercury engines.

When your Mercury engine breaks down, you don't have to buy a new car. A used Mercury engine that has been tested and certified can make your car run better, be more reliable, and get better gas mileage—all without the cost of buying a new one.

We get our used Mercury engines from donor vehicles with low mileage that have been checked out and tested to make sure they meet OEM performance standards. A good used engine will make sure that your Grand Marquis, Mountaineer, Milan, Mariner, or Sable runs smoothly and lasts a long time.


What Sets a Good Used Mercury Engine Apart?

A used Mercury engine isn't just taken apart and put back together; it's also checked, tested for compression, and certified to work like a new one.

Before shipping, each engine goes through:

  • Testing for leaks and compression
  • Checking the cylinder head and valves
  • Testing the oil pressure and analysing the fluid
  • Checking the mileage
  • Cleaning and packaging for installation
  • VIN check to make sure it fits perfectly

We check each used Mercury engine to make sure it is mechanically sound and ready to be installed.

Used Mercury engines give you the best value for your money because they come with real OEM parts at a great price.


You can trust our warranty and certification. Every used Mercury engine we sell comes with:

  • Depending on the model and mileage, parts are covered by a warranty for 6 to 24 months.
  • Confirmed reports of compression and leak tests
  • Proof of mileage
  • Guarantee that the fit will match the VIN
  • How to register a warranty and install it
  • Before shipping, each engine is tested to make sure it works well and is reliable.

Fits all Mercury models

We have used engines for almost all Mercury models made between 1995 and 2011, such as:


  • Mercury Grand Marquis
  • Sable Mercury
  • Mercury Milan
  • Mariner Mercury
  • Mountaineer Mercury
  • Mercury Montego
  • Cougar Mercury
  • Mystique of Mercury
  • Mercury Villager


Giving your VIN guarantees a perfect match for your year, model, and engine setup.


Benefits of Cost

A used Mercury engine costs 50–70% less than a brand-new OEM replacement, but it still works the same way.


Prices on average by model:

Mercury Grand Marquis 4.6L V8: $1,800 to $3,000

Mercury Mariner 3.0L V6: $1,700 to $2,900

Mercury Milan 2.3L / 3.0L: $1,800 to $2,700

Mercury Mountaineer 4.0L to 4.6L: $2,200 to $3,400

$1,800 to $2,600 for a Mercury Sable 3.0L

A good used Mercury engine will bring back smoothness and power without the high repair costs at the dealership.


Help with shipping and installation

Every used Mercury engine is professionally packaged and ready to be shipped safely anywhere in the country.

Liftgate delivery is available for homes and businesses.

Delivery takes 3 to 7 business days, depending on where you live.

Installer help and a list of recommended shops

We also include installation guides to make sure the warranty is valid and the engine is set up correctly."A tested used Mercury engine brings back performance, dependability, and value—without the cost of getting a new car."


When is it time to get a new Mercury engine?

If you have any of the following problems, you may need to replace your engine:

The block makes knocking or tapping sounds.

Loss of power or pressure

Build-up of oil sludge

Leaking oil or coolant

Overheating or a blown head gasket

Failure of the timing chain or bearing

Seizure of the engine or damage inside it

A certified used engine is often the best and most cost-effective choice.


Good for the environment and long-lasting

Picking a used Mercury engine is better for the environment because it cuts down on metal waste and emissions from factories. Reusing engines makes high-quality OEM parts last longer and has less of an effect on landfills and production.

  • Use oil and filters that the OEM recommends
  • Check the levels of the fluids often.
  • Don't speed up too quickly during break-in
