What is the difference between full power hydraulic steering and stock Mercury MerCruiser cable assisted steering?
Stock MerCruiser cable with power assist steering comes as standard hardware on most Alpha and Bravo drive applications. This system consists of a cable helm, a cable, and a power- assisted slave cylinder that is mounted to the inside drive transom plate. The slave cylinder gets power assist from an engine-mounted power steering pump and cooler. In this steering system the slave cylinder and cable steer the drive from the inside of the hull by the tiller arm. Even when new, there is play in the steering of the system.
