How Determine the Age of an Evinrude Boat Motor by Its Model Number


An Evinrude boat motor model number reveals specific information about the engine. It is generally 8 to 12 characters long. The codes in the model number represent the following information in order: style, horsepower, design features, shaft length, year built, and suffix/model run. Decoding the year-built code will reveal what year the engine was built in. Determining the age of an Evinrude boat motor is a simple process.

Things You'll Need

  • Model number tag
  • Identify the model number, which is generally found on a metal tag or sticker on the top edge of the clamp bracket or on top of the swivel bracket housing.

  • Locate the two-character year-built code, which is the second to last code, before the last, single-digit suffix/model run code.

  • The year built can be determined with the acronym "INTRODUCES," where each letter is associated with a digit that represents a part of the year-built code. Write out the word "INTRODUCES" vertically and next to each letter, write the digits 1 to 9 followed by 0.
    I 1
    N 2
    T 3
    R 4
    0 5
    D 6
    U 7
    C 8
    E 9
    S 0

  • Use this mapping to find out what the year-built code is. For example, the year-built code for the model E70PLEEA is EE. The letter E corresponds to 9, so the engine was built in 1999.

Tips & Warnings

  • The model number can also be found on the silver core plug or welsh plug on top of the powerhead.
