Hey Andy,
   
  Look into the specs for the prop you are interested in using.  They are redlined below the RPM where the tips go supersonic and the prop destroys itself.  While this is spectacular to watch, it is somewhat destructive.
  You can turn a smaller prop faster for this reason.

  Guys,
Regarding the 110hp Corvair engine going into the airboat - anybody have any idea, for a fixed pitch 1:1 driven prop - what would be the optimal rpm range?
Thanks,
Andy K.
