I'm glad to share my reasons to buy the Autostream Props.
Actually I bought two and a spare. Two, because my boat is a 38' catamaran with two 27 Hp Yanmar Saildrives. The excellent performance on the Autosteam in forward or reverse is actually enough to install these props.
However, my Cat sails faster then it motors. Therefore a fixed prop would create a lot of drag or if you let it spin it exceeds the Gearbox rpm and runs it hot with no cooling water pumped through. With the Autostream Propellers my Saildrive will last much longer.
