Optional Electro-Hydraulic Unit
For a correct use of our autopilot and for best performance, use hydraulic units suitable to the
vessel steering system.
The flow-rate is the most important parameter when you choose a pump: it should be calculated
to obtain a hard-over to hard-over time of about 12 seconds (±10/20%).
This is the formula to be used:
FLOW-RATE (liters/min.) = RAM-VOLUME (liters) x 5
FLOW-RATE (cc/min.) = RAM-VOLUME (cc.) x 5
The Continuous Running pumps can be installed on every kind of boat and are mandatory for
heavy or working vessels.
The Reversing pumps can be installed only on small pleasure vessels and, in any case, no bigger
than 15mt. (50 feet) length over all.
The electronics and the software provided with the autopilot are suitable to drive these two
popular types of rudder drives.
