Construction & Operation
The steering actuator is responsible for physically rotating the gearcase. It supports the transmission, and is bolted to the large bronze midsection plate. The steering and trim manifold is bolted to it, and it is controlled by hydraulic fluid pressure entering it from the steering portion of the manifold.
The steering actuator is a one‐piece housing with internal helical gears and a core assembly that operates similarly to a hydraulic piston. The hydraulic fluid diverted from the steering manifold applies pressure to one side of the internal core section causing it to move vertically. Applying pressure to the top side of the section causes it to move down and applying it to the bottom side causes it to move up. When this vertical movement occurs, the helical gears convert the vertical motion to rotary motion.
