Advanced Hydraulic Linear Actuator for Seamless Autopilot Control

The Octopus Autopilot Drives 38mm Bore Linear Drive with a 7" Stroke Mounted Pump (12vDC) is designed to deliver precise and dependable rudder control for vessels equipped with mechanical steering systems. This hydraulic linear actuator integrates a high-performance reversing pump and a marine hydraulic cylinder, ensuring smooth and efficient operation. The unit mounts directly onto the rudder tiller-arm or quadrant, allowing seamless autopilot engagement while enabling free rudder movement when the system is not in use.

This actuator offers a robust solution for offshore mariners, featuring a solenoid valve that locks the cylinder when autopilot is engaged. A compact, translucent oil reservoir simplifies fluid level checks, while its mechanical simplicity—comprising only five moving parts—enhances reliability and ease of service. Pre-filled with hydraulic oil from the factory, it requires no additional plumbing, making it a hassle-free addition to your vessel’s autopilot system.
