Boat Prop Pitch I Need To Find A 11 Spline 9 To 14 Pitch Prop For My Boat Motor?

I need to find a 11 spline 9 to 14 pitch prop for my boat motor? - boat prop pitch

I have a pontoon, I'm looking for a replacement propeller. It is necessary in 9 to 14 degrees with a 11-spline hub. I can not find an on ebay, they are all at least 13 or 15 spline spline. Any idea? I'm going on vacation in a few weeks and need a replacement for me to wear, which broke since I was the last time.
