Ram selection

Pump selection

The information above is presented as a general guideline for the proper selection of autopilot drive units. The drive unit requirement will determine which Advanced Control Processor (ACP) system is needed to complete the installation. The primary consideration in determining the drive unit type is boat displacement.

In addition to boat size, the proper selection of a hydraulic pump for hydraulic systems will be further defined by the total capacity or displacement of the boat's steering system.
