Hydraulic Considerations - Compact 2.1 L Pump
Different boats have different hydraulic considerations you must examine before mounting the pump or disconnecting any hoses.
Before starting the hydraulic installation, verify the type of hydraulic steering in your boat, and where to install the appropriate type of
pump.
If the hydraulic steering of your boat does not match the hydraulic layouts in this manual, contact Garmin Product Support.
