A manifold is disclosed for converting a manual hydraulic steering signal into a proportional electrical signal. The manifold is connectable between a hydraulic fluid supply, such a helm pump, and a hydraulic steering cylinder and includes a rotary actuator responsive to variations in the flow of hydraulic fluid from the fluid supply. The manifold is useful for converting small marine vessels from manual to power steering and for providing emergency manual steering in large tankers and the like.
