I have a Michigan wheel "Ballistic" prop for sale that I used on a 2000 Mercury 90hp. It is a small hub 13 1/8 x 21. The prop is only a couple of months old and is spotless and in the box. I am selling my boat and I had an old SS prop to put on it that ran as well. It is a deal at 245.00. email is email@example.com.
