Ray,

Are the numbers with a fin or wing keel?

I have the Gori 3-blade and am quite happy with it after nearly three
years. 
We've found it to make quite a difference in the boat's performance
under sail.

Below are measurements I made after I first got the prop (15 x 10) -
averaged over two runs (BK = boat knots)

RPM        BK/SOG    Overdrive BK/SOG
1300        2.9/3.2            2.9/3.2
1500        3.4/3.8            3.5/3.8
1700        4.2/4.4            4.2/4.3
2000        4.8/5.0            4.7/4.9
2300        5.5/5.7            5.7/5.9
2500        5.8/6.1            6.0/6.2
2800        6.2/6.4            6.5/6.7
3100        6.6/6.8            6.8/7.1 (max RPM)
3400        6.8/7.1
3450        6.9/7.1 (max RPM)
