    Karman, I'm trying to figure out the same thing. It was recommended to me to go up two pitch sizes if I were choosing a 4 over a 3 blade. That should even out the performance, but give more torque, so to speak. Can anyone verify that this information is correct?

    Here's a link to the i-boats.com prop guide. Look at the bottom of the page and the FAQ's should answer most of your questions.
