发明名称 Automatic rudder for outboard jet motors
摘要 An automatic rudder attachment for outboard jet motors. A rudder attachment is designed to provide steering capability at low or drifting speeds when the jet thrust is reduced and during reverse direction when the jet thrust is reversed. The rudder swings up to a retracted position when the jet motor is operating and provides sufficient thrust for steering. The rudder is pivotally attached over the jet nozzle whereby the water race effects the vertical swing of the rudder.
