Raymarine Evolution systems accommodate hydraulic, mechanical and power assisted stern drive systems. If you are not sure how to determine what type of steering system is installed on your vessel, please consult an authorized Raymarine dealer.
The Drive unit is the part that interfaces with your vessel's steering system to keep you on the right course. Raymarine has a broad range of drive units to match almost any type of steering system.
Hydraulic Linear Drives
Designed for larger mechanically steered vessels over 20,000kg, our hydraulic linear drives are self-contained hydraulic steering systems consisting of a reversing pump, reservoir and hydraulic ram.
A hydraulic linear drive unit connects to the rudder stock via an independent tiller arm. Accessory fittings from your steering system manufacturer may be required. Must be able to back drive steering system for the rudder.
