Re: decoding OMC serial numbers to get year.Mailing it is not a problem, but first do you see the link that is in quotes in my last post? Copy it, then paste it in your explorer browser. After getting to that site, click on view parts catalogue, then top left corner it should read Evinrude, click on the GO beside it, then click on your year in the left hand column, then your hp, which is of course 25, then your model number. Then click on I believe Midsection, you can from there enlarge the diagram with the little magnifying glass icon above it with the + or 1:1 on it. Let me know if this helps.

Evinrude Outboard Engine Serial Number Lookup

Evinrude By Serial Number

Have you ever wondered what the serial numbers on your outboard engine represent? Let's start with the first digit. Most likely you see an E or a J. Evinrude's system for decoding the year of manufacture is: I=1, N=2, T=3, R=4, O=5, D=6, U=7, C=8, E=9 and S=0. Pre-1980 Model number 85990R translates as 85 horsepower and '9' represents the year of the decade manufactured, in this case 1979.
