A method for controlling movement of drive units on a marine vessel includes receiving an operator request for a desired steering angle. A first drive unit's steering angle is set equal to the desired steering angle. A midpoint of a wetted surface area of the vessel hull is determined and a pivot line extending laterally through the midpoint and perpendicular to the hull's longitudinal axis is defined. A first intersection point of the pivot line and a line extending horizontally through the first drive unit's steering axis and parallel to the longitudinal axis and a second intersection point of the pivot line and a line representing perpendicular application of hydrodynamic force on the first drive unit are determined. A second drive unit's steering angle is set such that a line representing perpendicular application of hydrodynamic force on the second drive unit intersects the pivot line at the second intersection point.
