I have been asked to replace an impeller in a 2007 Johnson 20hp 4 stroke but I don't see that there was a 20hp that year. The motor doesn't have its transom sticker and the HP is blocked over by stickers required by the lake subdivision. The owner believes it to be a 2007 Johnson 20 4-stroke but he bought it second hand. Was a 20 hp 4 stroke sold by Johnson? I want to get the correct impeller. I am guessing it may be a 25 but I could be wrong.
