Garmin Class A Linear Drive Autopilot Unit 28500 Lbs

Offshore racing sailboats up to 28,500 lbs steer through quadrants with the Garmin Class A linear drive, which draws up to 15 Amps to deliver low-backdrive mechanical thrust across rudder stocks via 12V Reactor ECU networks.

  • Moves mechanical quadrant helms up to 28500 lbs
  • Low-resistance backdrive preserves light manual helm feel
  • Integrated mechanical feedback tracks precise rudder position
  • IPX5-rated housing protects internal mechanical gears

Connect a compatible mechanical tiller, cable, or steering quadrant to the Garmin Class A Linear Drive 010-11572-00. This 12V mechanical linear autopilot drive is specified for vessels up to 13,000 kg, or 28,500 lb, displacement. It is intended for fin-keel, full-keel, and displacement sailboat hulls, while the 9.5 kg, or 21 lb, drive weight should be included in mounting structure and access planning.

The Class A drive requires a compatible Garmin CCU, ECU, and control head as part of a complete autopilot system. It draws up to 15A during intermittent full-traversal loads and has an IPX5-rated housing. Integrated mechanical feedback is specified, but the selected steering arrangement, linkage geometry, actuator location, 12V circuit, and compatible ECU output must be confirmed before installation.

Drive and Steering Integration

This Garmin Class A unit is a drive only, not a full autopilot package. A compatible Garmin CCU, ECU, control display, heading sensor, steering linkage, and 12V electrical system are required. The drive must be matched to the actual vessel displacement, steering geometry, and the mechanical load of the existing tiller, cable, or quadrant arrangement.

Plan installation around the drive’s 9.5 kg weight, mounting structure, linkage travel, accessible service space, and 15A intermittent electrical demand. The IPX5-rated housing should be located according to Garmin installation guidance. Follow the complete Garmin system documentation for mechanical alignment, ECU wiring, CCU installation, control-head connection, and calibration.

Why Choose the Garmin Class A Linear Drive 010-11572-00

The Garmin Class A Linear Drive 010-11572-00 provides a 12V mechanical drive option for compatible sailboat tiller, cable, and quadrant steering systems. Its 13,000 kg displacement limit, 15A intermittent draw, IPX5 housing, 9.5 kg weight, integrated mechanical feedback, and requirement for separate Garmin CCU, ECU, and control-head components help buyers define a complete autopilot-drive installation.

Warranty and Support

Garmin warranty terms vary by product and region, and the supplied specifications do not provide a named warranty period for this Class A drive. can help you review vessel displacement, steering compatibility, mounting structure, 12V circuit capacity, 15A draw, and separate Garmin CCU, ECU, and control-head requirements before purchase. Review the applicable Garmin warranty coverage and documented package contents before ordering.

Before Ordering the Garmin Class A Linear Drive 010-11572-00

Confirm that your vessel has a displacement at or below 13,000 kg, or 28,500 lb, and uses compatible tiller, cable, or quadrant steering. You should verify the 9.5 kg drive mounting structure, linkage geometry, full-travel clearance, 12V circuit capacity for up to 15A, IPX5 installation location, and the required Garmin CCU, ECU, heading sensor, and control-head components before purchase.
