Type 2 (12V or 24V)
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 Steering Systems
Raymarine Evolution pilots connect to hydraulic steering systems using a rugged hydraulic pump matched to the capacity of the hydraulic steering system.
You'll need to find out the size (in cc) of the hydraulic cylinder ram(s) mounted to the rudder or inboard engined boats, or to the drive unit on outboard engined boats. Your steering system documentation will have this information.
