Where is the serial number on a Mercury outboard?
For most Mercury outboard engines 8hp and higher, the serial number is located halfway down the transom bracket on the right (starboard) side, just below the powerhead. On 6hp and smaller engines, it's found on top of the swivel bracket.
Many boaters take a quick photo of their serial number with their phone—this simple habit can save hours of troubleshooting when ordering parts.
We highly recommend you take a picture of your ESN tag and keep the photo on your mobile phone in case the tag becomes unreadable or if you need this information when you’re not near your boat.

What About a Mercruiser Serial Number?
On a Mercruiser sterndrive or inboard engine, typically, the tag is on the block near the starter. But, sometimes, it's down by the starter on the engine block, near the flywheel, or on the flame arrestor.
All too often, the ESN tag on a Mercruiser is not the easiest to find, so definitely take a picture and save it on your cell phone.

Why Do You Need to Know Your Mercury Serial Number?
Simply put, your Mercury serial number will allow you to identify and order the right parts for your engine model and year.
Mercury manufactures many, many different models and often variations of each model. While one thermostat might be the proper selection for some variations of a given engine model, there’s no guarantee that it will be compatible will all variations of that engine—knowing your Mercury serial number is the key.
As if matters weren’t confusing enough, sometimes Mercury will change an engine model design midway thru a given engine model year.
Therefore, Mercury Marine parts are often segmented by serial number ranges. Knowing your serial number will allow you to make sure that you are ordering the right parts, whether you are utilizing a Mercury engine schematic/Mercury outboard parts diagrams, the Mercury parts library, the complete list of Mercruiser parts library, or other resources.
How do I find out what year my Mercury outboard is by serial number?
To determine the year of your Mercury outboard, use the serial number on the engine and reference a Mercury Marine serial number-to-year chart. You can also enter the serial number into the Mercury Marine or PartsVu lookup tool to identify the exact year and model.
What is the serial number location on a Mercury 9.9 outboard?
The serial number for a 9.9hp Mercury engines is usually located on the top of the swivel bracket, which may require tilting the motor to see clearly.
Where is the serial number on a Mercruiser engine?
It’s typically found near the starter or flywheel, or on the flame arrestor. Always take a photo of it for safekeeping.
How can I identify my Mercury outboard by serial number?
Use the serial number lookup on the PartsVu Mercury Maintenance Library or the Mercury Marine parts catalog to determine the engine model and year.
What year is my Mercury outboard motor?
Once you locate the serial number, compare it against Mercury’s official serial number/year chart, or enter it online in a lookup tool.
