Flexofold
After much research on this subject I chose a three blade Flexofold, however the right prop for your boat may be something altogether different. Suggest calling Flexofold and discussing with them how you use the boat and what you would like to see improve. I was persuaded by the test results they publish on their site. I also had OK results with a two blade Martec. Sorry, but I can't see a good reason for a feathering prop. although I have friends that have them and like them.http://www.flexofold.com/default.htm
