Does anyone know of a single online source for checking previous motor model specs? I would like to be able to find the mfg, hp, #cyl, year and displacement. For instance; Evinrude or Merc, 80hp, 3 or 4 cyl, 1976-1992, 50-85 cu in. This is just an example of the info that I would like to help me shop for a used motor. I have tried several sites, but none offer the breakdown I want. Am I out of luck? Thanks for any input.
