EV-300 Solenoid Overview

The EV-300 system is for use onboard vessels with solenoid-controlled electro-hydraulic steering systems. The included ACU300 actuator control unit interacts directly with with the boat's steering gear solenoids, delivering accurate and reliable autopilot steering.

The EV-300 Solenoid autopilot also works with Raymarine and 3rd party constant running hydraulic drive units.   

The EV-300 Solenoid autopilot system includes our p70Rs color autopilot remote control with rotary controller, the EV-1 Sensor Core, the EV-300 Actuator Control Unit, and an Evolution autopilot cabling kit.
