Hydraulic Considerations - Compact 2.1 L Pump

Before starting the hydraulic installation, verify the type of hydraulic steering in your boat, and where to install the appropriate type of
pump.
Notice
If the hydraulic steering of your boat does not match the hydraulic layouts in this manual, contact Garmin Product Support.
