"Those 13x12 and 13x14.5 wheels would have the boat screaming at skiing speeds, so Im guessing theyre not installed on typical (non-tournament) boats."

The 13 X 12 was tested as a jump specific prop and will run higher RPM at 36 MPH, a bit over 4000 while the 13 X 14.5 spins 3750 RPM or so at 36. Lower RPM at that speed than say another brand of boat with another brand of propeller. The 13 X 14.5 is well suited to do it's slalom thing with the Ilmore and 1.26:1 trans.
