You didn’t indicate which horsepower 1955 Aquasonic, but the 7.5 hp decal set from discontinueddecals.com doesn’t have the words “Whispering Power”. The two 1955 Aquasonic 7.5 hp that I own have those words.
I have seen one or two nice originals that did not include “Whispering Power” on the decals, so they may have come either way.
