Find out moreHydraulic linear drive system for vessels with mechanical steering up to 22,000 kg (48,000 lbs.) displacement.
Hydraulic linear drive systems are self-contained hydraulic steering systems that allow Evolution autopilots to steer heavy displacement vessels with mechanical steering. Hydraulic linear drive systems consist of a high-performance reversing hydraulic pump, hydraulic steering ram, fluid reservoir and hydraulic lines. The system comes filled, bled and ready-to-install.
The included hydraulic steering ram will be anchored to the boat's structural members, and attaches to the rudder stock via an independent tiller arm. Accessory fittings from your steering system manufacturer may be required.
When selecting a hydraulic linear drive system, choose from either 12 or 24-volt models to match your boat's electrical system.
The Type 2 configuration is suitable for vessels with up to 22,000 kg (48,000 lbs.) displacement. All Linear Hydraulic Drive systems require an Evolution ACU-400 actuator control unit.
