Simrad NAC-1 Precision Hydraulic Pilot Pack, Up to 30 ft, Precision-9 Heading Sensor, PUMP-1 MkII 0.8L Hydraulic Pump, NMEA 2000, 12V DC

Overview

The Simrad 000-15951-001 is a NAC-1 Precision Hydraulic Pilot Pack that adds autopilot steering to a 12 V hydraulic system using the PUMP-1 MkII 0.8L reversible pump and a Precision-9 heading sensor.

It is recommended for boats up to 9 m (30 ft) in length and runs from a 12 V DC supply; the NAC-1 accepts 9 to 16 V DC and can drive up to 8 A continuous (16 A peak) to the steering drive.

The Precision-9 connects over NMEA 2000 and supplies heading and rate-of-turn data (plus or minus 2 degrees heading accuracy after calibration). 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.

Key features

• Complete hydraulic pilot pack with NAC-1 autopilot computer, PUMP-1 MkII reversible pump, and Precision-9 compass sensor
• Recommended for vessels up to 9 m (30 ft) in length
• 12 V system support with a 9 to 16 V DC input range at the NAC-1
• Drive output rated up to 8 A continuous with 16 A peak (1 second) motor control
• PUMP-1 MkII 0.8L geared reversible hydraulic pump for outboard-style reversible pump steering circuits
• Precision-9 outputs heading, rate of turn, pitch, and roll over NMEA 2000 and is rated IPX7
• NAC-1 rated IPX5 for splash resistance when mounted in a protected location
• NMEA 2000 Micro-C connectivity (single port) for networked displays and sensors
• Plug-and-socket connectors help keep wiring clean and reduce install time
• Auto/Standby dash button included for quick engagement and disengagement at the helm

Compatibility and fit

This 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.

The 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.

Installation and setup

Mount 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.

Install 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.

Use cases on board

This 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.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
