Using the pump from my old autopilot when upgrading to a Garmin Autopilot

Garmin offers two autopilots that can be installed on power boats, the GHP 10 and the GHP 12.

The GHP 10 Autopilot can not use any other manufacturer's pump. The GHP 10 will only support the latest Garmin pumps with the appropriate pump power and encoder connections. In order to find out if the GHP 10 can work on your vessel, please visit the GHP 10 webpage. From this webpage, please answer the questions in the box on the right side of the screen titled "Determine your specific GHP 10 configuration".

The GHP 12 Autopilot can be installed and use an existing third-party hydraulic pump. Please review the GHP 12 Installation Instructions to see if this pilot will work with your system.
