Common Question of Garmin Reactor 40
What does the Hydraulic Autopilot include?
The Garmin Reactor 40 Hydraulic Autopilot package includes a GHC 50 autopilot instrument according to the listing. Confirm the hydraulic pump, steering-cylinder compatibility, heading sensor, hoses, wiring, battery, software, and hydraulic autopilot system requirements before installation.
What steering system does it need?
It requires compatible hydraulic steering equipment and a correctly sized pump for the vessel’s steering cylinder. Confirm cylinder volume, hydraulic fittings, hoses, pump capacity, control unit, battery, and calibration before operation. Correct sizing supports reliable heading control.
Is it an anchor windlass?
No. The Reactor 40 Hydraulic Autopilot controls vessel steering and does not operate a gypsy, drum, chain, or anchor rope. It is not an electric anchor windlass. Verify separate equipment for anchor retrieval.
