A method for controlling waterjet-powered watercraft wherein: a pair of electric actuators 12 and an associated pair of motor controllers 16 are mounted inside a housing of the watercraft; the motor controllers and electric actuators are powered using the watercraft's main power supply; a steering arm (30, Fig 3) used to steer the watercraft is connected with the pair of electric actuators; a reverse bucket (20, Fig 1) is used to reverse the travel direction of the watercraft; a positioning command from a user is sent to a first of the electric actuators; and once the first electric actuator receives the positioning command, the second electric actuator applies the same current as the first electric actuator, but in the opposite direction, to provide respective forces that cause the steering arm to turn. A waterjet propulsion system wherein a feedback system is integrated into an electric actuation system as at least one encoder is also disclosed.
