Raymarine ACU (Actuator Control Unit) Series
The Raymarine ACU series provides crucial power and control to Evolution autopilot drive units for a wide range of vessels and steering systems. Each model offers specific drive output capabilities tailored to different boat sizes, steering types, and power requirements—from small hydraulic drives to large mechanical and electric solenoid-controlled steering systems.
Models: E70098 (7A) | E70430 (12A) | E70098 (15A) | E70098 (30A)

Additional Details
-
Drive Selection: Depends on boat displacement, steering system type (hydraulic, mechanical, solenoid), and power needed for reliable steering under expected conditions.
-
Hydraulic Steering: ACU-100 and ACU-150 suit smaller to medium hydraulic systems; ACU-200, ACU-300, and ACU-400 when more power or advanced drive compatibility is needed.
-
Mechanical Steering: ACU-200, ACU-300, and ACU-400 increasingly accommodate larger or more power-demanding systems.
-
Power Supply: Operates on 12/24 V DC power with broad voltage tolerance.
-
Connectivity: SeaTalkNG interface for integration into Raymarine autopilot networks.
-
Environmental Protection: Drive electronics rated IPX6 for marine durability.
Typical Applications
| Model | Steering Type | Vessel Size and Use |
|---|---|---|
