Re: aq125a 270 rotation ?
The outdrive is designed to operate either direction. So just by a standard rotation prop. If you shift into forward but go backward, its an easy change to the shift linkage to make the switch.
The prop choice is really more for the prop forum. If you go to that forum and post your question, you'll get your answer. Make sure to post all the info about the boat size, horsepower, etc, to try to figure out what you need.
Welcome to iboats, btw.
