I would consider a 4 blade solas propeller in as close of a diameter as you can get to what you have currently, but 2 inches lower in pitch.  The solas prop will have thinner blades, but they will flex less than a standard 4 blade aluminum.  The prop is cupped as well, which will help hold the water better.  The ears will be a little more rounded, but that adds to handling.    
  
In my experiences with them, their props perform closer to a steel prop.
