Boats are not like cars, when you turn the wheel the stern swings out in the direction of the turn. To be able to do the "standing Turn" you need to have forward motion and then turn the wheel fully to kick the stern out. Utilizing prop walk is helpful but realize that even boats with very little prop walk can perform the maneuver. Once you kick the stern out just shift into reverse and it slows forward motion while maintaining the sliding motion of the stern. As the motion of the stern starts slowing down you may shift back to forward and repeat the procedure while keeping the wheel turned fully. Once you have adequate turning room just shift to forward and ease the wheel in the opposite direction to gain your course. To find out which side your boat favors you need to insure that wind and current will not be a factor and set your rudder straight and ease the boat into reverse at idle speed. The boat with little or no outside interference will favor the side of the prop walk. Once you know which side the prop walk favors then you can use it your advantage by starting the "standing turn" in that direction as the walk will enhance the swing out motion of the stern. Some boats will perform the maneuver better than others and it is good to practice in an open space so you may learn its limitations and how the introduction of current and wind may affect the maneuver.
