Raymarine EV-400 Power Evolution Autopilot

Description

The Raymarine EV-400 Power Evolution Autopilot is a high-capacity autopilot electronics pack for larger powerboats with compatible hydraulic or mechanical steering. It includes a p70Rs control head, EV-1 nine-axis sensor core, ACU-400 high-current actuator control unit, and Evolution cabling kit, but it does not include a steering drive. A separately selected Type 2 or Type 3 hydraulic pump, linear drive, rotary drive, or other approved actuator is required.

The ACU-400 supports 12V or 24V systems and delivers up to 30A continuous drive output, making it suitable for higher-current steering actuators that exceed the capacity of smaller Evolution ACUs. The p70Rs provides a rotary-dial autopilot control interface, while the EV-1 sensor core supplies heading and motion data. Confirm the actual steering system, drive load, hydraulic-cylinder volume where applicable, and complete installation requirements before purchase.

Key Specifications

• High-capacity Raymarine Evolution autopilot electronics pack for compatible larger powerboat steering systems.
• Includes p70Rs control head, EV-1 sensor core, ACU-400 actuator control unit, and Evolution cabling kit.
• Does not include a hydraulic pump, linear drive, rotary drive, steering actuator, or hydraulic plumbing.
• Supports 12V or 24V DC electrical systems.
• Provides up to 30A continuous drive output through the ACU-400.
• Compatible with correctly selected Type 2 and Type 3 hydraulic pumps, linear drives, and rotary drives.
• Uses SeaTalkng networking with NMEA 2000 integration through compatible network connections.
• Requires protected bulkhead mounting for the ACU-400 and flush mounting for the p70Rs control head.

System Integration

This is a core autopilot package rather than a complete steering system. Select the drive unit based on actual steering type, vessel displacement, hydraulic-cylinder volume, system pressure, required rudder force, drive-current demand, and manual-override requirements. The selected actuator must remain within the ACU-400’s 30A continuous output rating.

Virtual Rudder Feedback may reduce the need for a separate physical rudder-feedback sensor on suitable installations, but it is not appropriate for every vessel or steering configuration. Verify whether the installed steering system requires physical feedback before ordering the complete system.

Installation Considerations

Install the ACU-400 in a protected, dry, accessible location with sufficient ventilation and space for high-current wiring. Mount the EV-1 sensor clear of magnetic interference, high-current cables, engines, speakers, and severe vibration. Plan the p70Rs helm cutout, SeaTalkng backbone, drive wiring, circuit protection, hydraulic plumbing where applicable, and manufacturer-required dockside setup plus sea trial.

Before Ordering

Confirm vessel steering type, selected Type 2 or Type 3 pump or approved mechanical drive, hydraulic-cylinder volume and pressure where applicable, 12V or 24V supply, 30A continuous drive capacity, ACU-400 mounting space, p70Rs helm-panel space, EV-1 sensor location, SeaTalkng network, feedback requirement, circuit protection, and all required drive and installation components before purchase.
