Kevin-

I'm not sure what you are trying to prove. If you know what motor it was and equipment, then fine. However, I would find out exactly what prop you need. There are probably only a few places to get them - APC and Supercool have been suggested already. You might want to try them. However, unless I am mistaken, no MVVS that I know of puts out the power of a Nelson, or similar. Having the right prop doesn't always equal speed. You need the motor to turn it.
