Where can I find my Mercury outboard serial number is a question we’re asked all of the time because it is an essential piece of information when ordering parts for your outboard.
For Mercury outboard engines 8hp and higher, your engine serial number (ESN) tag can be found halfway down the transom assembly on the right (starboard) side, just below the engine’s powerhead.
For engines 6hp and lower, you can find your Mercury outboard serial number on the top of the swivel bracket. You may need to tilt the engine up and trim it to the left to see the ESN tag clearly.
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.

Hi Jim, Thank you for your inquiry. Unfortunately, the serial number 1F10462EK you provided doesn’t appear to produce any immediate results in our lookup system. It’s possible that there may be an issue with how the number was entered, or it may be from a series that’s harder to cross-reference. If you’d like, you can take a clear picture of the serial number plate and send it to us at partsvu@partsvu.com. The serial number plate can typically be found on the mounting bracket or inside the top cowling of your motor. This way, we can make sure we have the correct number and provide you with the most accurate information. Based on the format of the serial number you’ve given, Mercury outboards starting with “1F” are typically from the 1999 model year, but we’d need to confirm if the serial number you provided is valid to be sure. We apologize for any inconvenience this may have caused, and we hope this helps! Best regards, Markine D.

Good day.
Could you help me clarify a doubt, I work as an insurance expert, I inspected a boat with a Mercury 400 CXL (Racing) engine or model 14000106A with serial number 3B538984, in the CE part now it does not say year, with that data how do I know the true year or where is there a search engine to find out the year, I know it is 2024 from the invoice, but if I didn’t have it how would I check the year?
Thank you for your attention and I look forward to your response.
Best regards
Jose
