With a compatible Simrad multifunction display on the same NMEA 2000 network, the system supports steering to a set heading, course, or route, along with turn patterns.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eComplete hydraulic pilot pack with NAC-1 autopilot computer, PUMP-1 MkII reversible pump, and Precision-9 compass sensor\u003c\/li\u003e\n\u003cli\u003eRecommended for vessels up to 9 m (30 ft) in length\u003c\/li\u003e\n\u003cli\u003e12 V system support with a 9 to 16 V DC input range at the NAC-1\u003c\/li\u003e\n\u003cli\u003eDrive output rated up to 8 A continuous with 16 A peak (1 second) motor control\u003c\/li\u003e\n\u003cli\u003ePUMP-1 MkII 0.8L geared reversible hydraulic pump for outboard-style reversible pump steering circuits\u003c\/li\u003e\n\u003cli\u003ePrecision-9 outputs heading, rate of turn, pitch, and roll over NMEA 2000 and is rated IPX7\u003c\/li\u003e\n\u003cli\u003eNAC-1 rated IPX5 for splash resistance when mounted in a protected location\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 Micro-C connectivity (single port) for networked displays and sensors\u003c\/li\u003e\n\u003cli\u003ePlug-and-socket connectors help keep wiring clean and reduce install time\u003c\/li\u003e\n\u003cli\u003eAuto\/Standby dash button included for quick engagement and disengagement at the helm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis pack is intended for boats with hydraulic steering that can accept a reversible pump in the steering circuit. The included PUMP-1 is compatible with SeaStar manual helm pumps up to 14 cubic inches, which is a useful sizing check on many outboard and sterndrive installations.\u003c\/p\u003e\u003cp\u003eThe system uses NMEA 2000 (Micro-C) to connect the heading sensor and compatible displays. Plan your backbone so it reaches the helm, the NAC-1 mounting location, and the sensor mounting location; the included network accessories cover common extension and termination needs, but larger installs may require additional backbone parts.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eMount the NAC-1 on a bulkhead inside a console or locker where it stays protected from direct spray but still has airflow and service access. Power it from your 12 V DC distribution with an appropriate 20 A fuse and keep battery-negative returns clean to avoid voltage drop when the pump is working.\u003c\/p\u003e\u003cp\u003eInstall the Precision-9 away from magnetic sources such as speakers, large motors, and steel hardware, then complete calibration during setup. Plumb the PUMP-1 into the hydraulic lines using the ORB steering fitting kit, bleed the steering system thoroughly, and perform a sea trial so the autopilot can learn your boat.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis setup fits boats where you want hands-off steering on longer runs, trolling passes, or while following a route and keeping a close watch on traffic and gear. It also suits installs where adding a separate rudder feedback sensor is not practical, since the NAC-1 supports virtual rudder feedback on many outboard and sterndrive planing hull setups.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eNAC-1 autopilot computer\u003c\/li\u003e\n\u003cli\u003eMKII PUMP-1 (12 V, 0.8L) hydraulic pump\u003c\/li\u003e\n\u003cli\u003eAutopilot pump fitting kit for ORB steering system\u003c\/li\u003e\n\u003cli\u003eAuto\/Standby button (metal)\u003c\/li\u003e\n\u003cli\u003eN2KEXT-2RD 0.61 m (2 ft) NMEA 2000 cable\u003c\/li\u003e\n\u003cli\u003eN2KEXT-6RD 1.82 m (6 ft) NMEA 2000 cable\u003c\/li\u003e\n\u003cli\u003eN2KEXT-15RD 4.55 m (15 ft) NMEA 2000 cable\u003c\/li\u003e\n\u003cli\u003eTR-120-KIT terminators (1 male and 1 female)\u003c\/li\u003e\n\u003cli\u003eMicro-C power cable (no T-connector)\u003c\/li\u003e\n\u003cli\u003eLow-loss NMEA 2000 4-way joiner\u003c\/li\u003e\n\u003cli\u003ePrecision-9 compass\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Simrad","offers":[{"title":"Default Title","offer_id":52269696876725,"sku":"QBP756549","price":1829.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1300991_qbp756549.jpg?v=1771545285","url":"https:\/\/www.qualityboatparts.com\/products\/qbp756549","provider":"Quality Boat Parts","version":"1.0","type":"link"}
