Numerals following the
motor model code indicates the start of the manufacturing date for that series
motor. For example, 0410 is used for motor series that were manufactured
starting in April of 2010 until the date of the next series. If you do not
know the manufacturing date you can find this information on the same label as
your motor model and serial number.
Where available, the serial numbers follow the
manufacturing date numerals. Your exact serial number will not be listed,
rather they will fall into the range of serial numbers given. Knowing your
serial number (also known as your “Primary ID” is important in making sure you
get the correct parts for your motor as parts may change from one manufacturing
series to the next. You can find
your serial number on the sticker on your bracket following the engine’s model
code or on any paperwork provided with the motor sale. Your exact model
info will not be listed in your owners manual or your service manual.
