For sale is a very good condition ready to go Bronze propeller 16" diameter x 8" pitch 3 blade.  So you need more pitch, just re-pitch it.  Nice solid bronze prop.  

1 1/4" tapered bore.  Blades are broad at 7" across.  Just removed from my 42' sailboat.  I had this prop on the boat and running fine.  No nicks or bends.  Pitch was incorrect so purchased a new prop. This prop was professionally balanced and pitched to 8 inches in May, 2015.  Standard 1/4" key-way.  Thanks for looking.
