The DD15 Direct Drive is a very strong and compact autopilot drive and more efficient than hydraulic and most electromechanical autopilot drive units.
Linear drives are the most preferred on sailboats.
Hydraulic linear drives designed for boats with mechanical steering systems such as wire and cable steering.
All hydraulic linear drives are also available in a split version with the pump separated from the ram and interconnected with 1m (3ft) hoses.
The MSD50 Linear drive is particularly designed for stern drive or I/O boats with power assisted steering.
Hydraulic systems normally comprise of two main components, a steering wheel pump and steering cylinder(s).
The linear motion of the cylinder rod is transformed to a rotary motion by the tiller, which turns the rudder shaft and rudder.
Hydraulic steering systems are now being used in every category of small vessel.
The SD10 Sailboat Drive system makes it easy and economical to install an autopilot on small to medium size sailboats.
