model/year?

[just ducky]

I have a 15hp Evinrude that I got from a friend, and the ID plate is missing. My best guess is it's from the late 70's. Is there another way to tell the year of the motor other than the serial number? Trying to find some replacement parts, and without the year I'm a bit challenged.

Nevermind. Someone else told me about the "freeze plug" which I had never known about. So I've figured it out...mine is a 1974.
