Abstract: A boat stabilizing rudder system is disclosed. A rudder is formed of planar sheet material positionable in a vertical orientation. A vertically positioned support rod has a lower end, an upper end and an elongated central extent therebetween. The lower end is formed with plates adapted to be coupled to the rudder. The upper end is mounted on a driven gear adapted for rotation about a vertical axis. A bracket has an aperture adapted to receive the intermediate upper extent of the rod beneath the gear for rotation of the rod with the rudder therebeneath about a vertical axis. Also included is a drive box with a motor, a driven shaft, and a drive gear in driving contact with the driven gear. The bracket also has an aperture therethrough with a first pivot pin constituting a hinge. A pivot box has horizontally disposed second apertures therethrough with a second pivot pin positioned through the second apertures. A positioning rod has an exterior end with an outboard aperture receiving the first pivot pin.
