motor calculator

I found this motor calculator. http://brantuas.com/ezcalc/dma1.asp

It may be of interest to someone. There are some motors listed that are boat related.

There is also a FE calculator out there. It is strictly for boats and does everything. Although sometimes I do question the accuracy. I can't remember where I got it from.

I have MotoCalc but I wish I could find some way to mod the setup files to work for boat props instead of air props... any physics or nautical engineer sorts out there that can give me the property differences between "air" and water!? LOL! :D

I'm not an engineer but it seems that the things that would need to be changed, the density factor between air and water and the surface area of each prop.
