Re: Looking for Model Year Evinrude 60 hp
On that model, there should be a heavy duty sticker at the top portion of the steering swivel bracket, between the swivel bracket and the engine's exhaust housing ( the long housing between the powerhead and the lower unit).
That sticker would have the model and serial number on it. Also, check the powerhead for as quarter sized core plug (looks like a small freeze out plug) that may have those number on it.
The numbers you listed are most likely casting numbers.
