Autopilot Selection Guide:

It is important to select the correct size of pump as it directly influences the ability of the autopilot to steer the vessel. If the pump is too large, the vessel may over steer and will use more power; if it is is too small then the autopilot may struggle to maintain a course.

“Hard Over Time” is the time that the pump takes to drive the rudder from port to starboard. An autopilot drive perferably gives a “Hard over time” of 10 to 14 seconds unless otherwise specified by the autopilot manufacturer. The type of vessel to be steered must be considered as the “Hard over time” may be faster on lightweight planing craft / modern yachts and slower on displacement power boats/ long keel yachts.

To use the table in our product pictures, you will need to know the volume of your steering cylinder, then select the "Hard over time" that you require. Follow the column down until you approximately match your cylinder volume and then select the pump on that row. If your cylinder has a smaller volume then it will have a faster “Hard Over Time”, but if it is larger, it will have a slower “ Hard Over Time”.
