Proper Oil Mixture

Is there a book or a place online that will give the proper oil to gas mixutre for different motor years and speeds? I have an OLD (not sure of year but in the 60's) Evinrude/Johnson 10 or 15 HP that I need to make sure and mix the parts properly for. I wnated to compare different years and HP to make sure that I don't mess up the motor by improperly mixing the fuel and oil.
