Abstract
A power steering apparatus for steering an outboard engine on a boat has a hydraulic cylinder unit for angularly moving a steering arm of the outboard engine, and a hydraulic pump actuatable by a motor for supplying a hydraulic pressure to the hydraulic cylinder unit. The motor is controlled by a motor driver which supplies a first amount of electric energy to the motor when the outboard engine is not steered, and supplies a second amount of electric energy, larger than the first amount of electric energy, to the motor when the outboard engine is steered.
