Mercury Marine & MerCruiser Part Number Formats for Online Searching
How to Enter Your Mercury Marine or Mercruiser Part Number
Due to the variety of Mercury Marine part numbering formats if you don’t initially locate your Mercury part when using the website search feature, try removing the prefix and/or suffix of the Mercury or Mercruiser Part number you trying to locate. Unlike Suzuki Outboard Part Numbers and Yamaha Outboard Part Numbers, a;though its is normally shown with the Part Numbers Mercury Marine does NOT include the prefix as part of the actual part number. For example rather than searching for p/n 84-123456A 8 try searching for just 123456 and then locate your particular part number from all of the available matches that are returned in the search results. This allows you to drill down to the correct version of the part you are looking for. In many cases you’ll notice the part number you are searching for has changed and been “superseded” up to a newer, more current version of the part.
Example: Mercury Marine part number 10-40095 16. If you enter the part number exactly as formatted including the ‘-‘ after the prefix and the ‘space’ before the suffix, it will return the proper search result. However if you enter this as 10-4009516 (without the space before the 16 suffix) it WILL NOT show the proper search results. Alternatively, if you enter just the 40095 it will pull up all variations of Part Numbers that use this string of numbers; not just Mercury but other manufacturers as well. Although this can be a problem when the “shortened version” of the Mercury part number you enter returns a high volume of possible matches, but in certain cases it’s the only way to drill down and determine the current version of the part number you are searching for. You can then select the link to the matching product/part number to see the full list of models the part number is used on so you can verify if your particular engine or sterndrive model is shown to be associated to that part number.
*Example #1 – Searched using the EXACT part number “10-40095 16” including the “10-” prefix and ” 16″suffix
*Example #2 – Searched only the base part number “40095” w/o the “10-” prefix or ” 16″ suffix
The History of Mercury Marine Part Number Formats & Changes
Mercury Marine and MerCruiser used a specific part numbering system for many years, however this has since changed. Most of the newer Mercury and Mercruiser part numbers will follow the “8M1234567” style numbering format. Up until a few years ago Mercury Marine Part Numbers had a PREFIX followed by a set of numbers ranging between 4 and 6 digits which may or may not have then been followed by a SUFFIX.
Prefix Usage: The purpose of prefixes was to designate marine part classification codes for internal company purposes. The following 4 prefixes are just a few of the many prefixes Mercury Marine utilized.
- 10 – prefix applied to Fasteners
- 11 – prefix applied to Nuts
- 12 – prefix applied to Washers
- 22 – prefix applied to Fittings
- 32- prefix applied to hoses, tubes and lines
Suffix Usage: These were used to indicate products such as a “C” being used to designate a casting or “A” being an assembly or Q representing the Quicksilver version of the part. For example 123456A1 could represent an assembly level part made from a 123456C casting. Then the 123456A2 could represent a slightly different assembly version altogether that was made from the same casting. For example, the A1 may part have included a certain fitting already inserted into the casting while the A2 version included the same casting but with a different size of fitting.
- “C” (Casting)
- “A” (Assembly)
- “Q” (Quicksilver Items)
- “T”
- “K” (Mainly Service Maintenance Related Items)
- “A1”
- “A 1” (Note the character space after the A and before the 1)
- “1”
- ” 1″ (Note the character space before the 1)
