Other companies make these power thrusters that are configured differently and resemble small wings. A friend of mine has one on the outboard of his Nimble Peep Hen and he said that it works great and offers more power. This particular power thruster would appeal to me more because it fit's around the propeller and would maybe offer some protection to my tip-up rudder blade on my O'Day 222. Too many times my rudder would suddenly pop up and come in contact with my outboard prop, and too many times, I had to fix my rudder blade. I think that maybe I'll look into purchasing one myself if I can get one cheap enough.Joe
