Spin props out with the drives toed in (front of engines closer than rear of engines) between 1/8-1/4".
When running you want your drives to line up straight like this: I I
With props turning out, the waters resistance to the blade is pushing the prop toward the centerline of the boat (prop torque). When the rear of the prop shaft is pushed toward the center, the front of the prop shaft has to open up or move away from the centerline. So you go from / \ to I I
