Once again, the number on the round aluminum core plug is the serial number.  It would be very hard to match it up with an actual model number, most of those records are gone, along with the computer programs.   The “E” in the serial number means the engine was produced in the Milwaukee Evinrude plant, even though it is a Johnson.    The first two numbers of the serial number being 35 is purely coincidental.  OMC did not produce 35hp models like this until 1976, and I could easily tell if it was one of those just by looking at your pictures…

Use the 1972 Johnson 20-25hp parts book for most basic items.  If you can see through the decals/emblems on the cover, and you see “25” being mentioned, then it most likely it a 25hp….
