Evinrude model years from serial numbers?

[Canoe2]

I had a couple of motors appear in my driveway from somebody, but they don't seem to have any model numbers, nor can i find them stamped on the blocks. I suspect one is a 10 and the other an 18. Serial numbers are 10022 11507 and 5524 51080. Is there any place i can look these up or could someone point me to where the block may be stamped? Thanks, Tim

10022 is the model number, as is 5524. That makes them 1961 10hp and 1962 5.5hp respectively.
