Claim Text:
1. A toe angle control system for outboard motors, comprising: a plurality of outboard motors mounted on a body of a ship; a ship speed sensor configured to detect a speed of the ship, and a trim angle sensor configured to detect trim angles of the outboard motors as running states of the ship; a lifting force detector configured to detect a lifting force generated along with propulsion of the plurality of outboard motors; a memory unit configured to store therein a toe angle data table in which the running states of the ship detected by the ship speed sensor and the trim angle sensor, and the lifting force detected by the lifting force detector are associated with each other for each toe angle of the outboard motors; and a controller configured to adjust a toe angle of the outboard motors based on the running states of the ship detected by the ship speed sensor and the trim angle sensor, and the toe angle data table stored in the memory unit, wherein the toe angle data table associated with the running states of the ship for the plurality of outboard motors are mounted on the ship is stored in the memory unit, and wherein the controller selects a toe angle of the outboard motors so as to minimize the lifting force depending on the speed of the ship and the trim angles of the outboard motors detected by the ship speed sensor and the trim angle sensor.
