This Power Assist unit uses an electronically controlled hydraulic pump to provide steering power to your SeaStar steering system. The hand-operated circuit elements control the hydraulic power element remotely to control either a tiller or an outboard with optimum precision. It’s compatible with most steering stations and most autopilots.
In a typical installation, the helm steering station has a pump, which feeds the Power Assist unit in the aft of the boat. The Power Assist unit increases hydraulic pressure in steering lines for optimum control and responsiveness. In the event of a power loss, the system will revert to a manual hydraulic system. Peak operating pressure of 1000psi with average draw of 3A (Single Rudder OB) or 8A (Twin Rudder IB), peak draw of 55A @ 12V.
