      That depends on want you want to do. Like a Crossflow or like a river boat the efficiency is very poor and the power is very low because the area presented to

        Like a Crossflow or like a river boat the efficiency is very poor and the
        power is very low because the area presented to the water is low.
        Unless you have a wide blade area which means a wide wheel.

        It is better to have a "propeller" presenting a good area to the water.

        Now, what do you want to do ?.
