Warranty FAQs

How do I get warranty coverage for my engine?

Your engine must be registered with Mercury Marine in order to have warranty coverage. If your engine is not registered with us, it will not be covered by any warranty.

How do I register my engine with Mercury, to ensure that it has warranty coverage?

If you purchase your engine or boat from an authorized Mercury Marine dealership, they should process the warranty registration and provide a copy during pre-delivery review.

If you purchase your engine (30hp and below) from a retailer or over the Internet, you will need to complete and return the Warranty Registration card found in the box with the engine.

In either case, your engine must be registered with Mercury within fifteen (15) days from the date of purchase.

If I purchase a used engine or boat from someone, can the warranty be transferred to me?

To transfer the remaining factory warranty into the new owner’s name, please fax a copy of the bill of sale to 920-907-6663, email to registration_support@mercmarine.com, or mail to:

Mercury Marine
Registration & Warranty Dept.
P.O. Box 1939
Fond du Lac, WI  54936-1939

Be sure the following information is included on your bill of sale:

  • Date the engine was purchased
  • Engine serial number
  • Your name and address
  • Your telephone number

When does my warranty coverage begin?

Your new Mercury outboard or sterndrive is covered by our factory warranty from the date the product is first put into service or your date of purchase, whichever occurs first – provided that it is registered with us. For example, a Verado sold and registered in July 2010 will have a three-year limited, non-declining warranty through July 2013.

What is the standard warranty on Mercury outboards?

All Mercury outboards have a standard limited, non-declining warranty. The length of warranty coverage can be one, two or three years depending on the model. Please refer to our Warranty Coverage Chart or contact your local authorized Mercury outboard dealer for more details.

Will modification of my engine or sterndrive void the warranty?

The warranty does not apply to damage or failures caused by use of an accessory or part not manufactured or sold by us. See the appropriate MerCruiser warranty policy for your product or in your Operation, Maintenance & Warranty manual.

What is the standard warranty on MerCruiser sterndrives?

MerCruiser sterndrives, inboards and tow sport inboards have a standard limited, non-declining warranty. The length of warranty coverage can be one, two or three years depending on the model. Please refer to our Warranty Coverage Chart or contact your local authorized Mercury MerCruiser dealer for more details.


Certain boat brands, whose manufacturers have met the requirements for the Mercury Installation Quality Certification Program, carry an additional year of warranty on the MerCruiser engine. The program is the first of its kind in the boating industry and the only comprehensive manufacturer-installation certification system. This rigorous system identifies areas of improvement and implements resolution before the product leaves the factory. With the addition of the Installation Quality Certification Program, Mercury not only advances the marine industry to new standards but also ensures that you get the highest-quality products possible so your boating experience will be the best it can possibly be.

Are my Mercury gauges, controls, and rigging components covered by warranty?

Mercury’s standard warranty coverage could also extend to the controls and rigging components on your boat. If the boat builder used genuine Mercury Precision Parts when installing the engine on your boat built after May 2007, the warranty coverage for those rigging components matches the total standard warranty of your engine (up to three years for Mercury outboard-powered boats; one, two or three years for MerCruiser-powered boats). This means you could have up to an additional two years of control & rigging component coverage.

To find out if your gauges, controls and rigging qualify for the additional warranty, please contact your local Mercury dealer.

Will the use of fuels containing ethanol void my engine warranty?

Fuels containing up to 10 percent ethanol are considered acceptable for use in Mercury engines. Fuels containing higher levels of ethanol are not considered acceptable for use, and the use of fuels containing ethanol higher than 10 percent can void the warranty.

Is there a warranty against corrosion?

All Mercury outboards and MerCruiser sterndrives, inboards and tow sport inboards come standard with three years of limited corrosion protection.

MerCruiser SeaCore sterndrives come standard with four years of limited corrosion protection.

Can I purchase additional warranty coverage?

Mercury Product Protection plans are available for purchase on select models to extend the factory-backed coverage on your engine. Combined, the standard factory warranty and a Mercury Product Protection plan can give you up to seven years of coverage.

Visit the Mercury Product Protection section of our Web site for more information.

What does ‘non-declining’ mean?

‘Non-declining’ means that the warranty coverage is the same on the last day of your warranty as it is on the first. The coverage doesn’t decline based on the age of your engine, or the number of hours you’ve put on it.

If I need service work done, how do I file a claim?

Any warranty work done on your engine needs to be done by an authorized Mercury dealer. Your dealer will perform the work on your engine and file the claim with Mercury for you. There is no need for you to file a claim.

Is the warranty provided by a third party?

Mercury warranty coverage is factory-backed. Your dealer works directly with us, so there are no third-party claims to file – and no adjusters to contend with. This simplifies the claim process and gets you back onto the water quicker.

How can I tell if my engine is still covered by warranty, or how much coverage is left?

Using the serial number of your engine, your local authorized Mercury dealer can quickly and easily check your warranty coverage. They can verify that your engine is registered with Mercury, whether it is covered by our standard factory warranty, and if there is any additional promotional coverage or if it is covered by a Mercury Product Protection plan.
