Mark, I'm sure you mean Villain not Vision......LOL! Yes, it was designed around the K&B. Grim/Mike was fairly specific about how far he liked the prop to be from the transom & recommended minimal setback. I could be wrong, but I believe he offered a mount that was just a thin plate that allowed vertical adjustment that was only about 3/16" thick. The OS lower does set the prop back a lot further than a K&B. I have never run a mount with a lot of set back or an OS on any of my Villains so I can't speak for the results.
