A steering control system for ski boat with an inboard motor and a single, non-steerable propeller. The control system augments the traditional aft rudder with a forward rudder (located immediately in front of the propeller), and controls one or both rudders to improve steering when backing and in low forward speed conditions. The control system may control only the forward rudder, while the pre-existing controls operate the aft rudder, or optionally controls both rudders. The rudder angle control algorithm calculates proportional rudder angles based on helm and throttle settings, or optimal rudder angles based on more sensed conditions including the operator's helm and throttle controls, the ski boat's direction and speed, propeller RPM and thrust direction, and each rudder's angle. An electronic controller sends control signals to the rudders to achieve the optimal rudder angles.
