B&G Hydraulic Ram to 12V

Discover the reliability of a fully integrated hydraulic ram drive designed specifically for smaller vessels seeking seamless autopilot performance. This compact 12V unit transforms manual steering setups into efficient, hands-free navigation, perfect for sailors who demand precision without the clutter of external components. Whether you’re dodging waves on a coastal cruise or holding course during long passages, its powerful thrust ensures steady control even in demanding conditions.

Built for boats where every ounce of efficiency counts, this ram integrates a self-contained pump, motor, cylinder, clutch, and reservoir—no messy hoses or separate tanks to install. It engages effortlessly in Power Steer mode during manual steering issues, giving you backup confidence at sea. Ideal for vessels up to 19,000 lbs fully loaded, it handles the real-world weight of provisions, fuel, and water that often exceeds lightship specs.

Standout Performance and Build Quality

• Robust Thrust: Delivers up to 771 lbs of force intermittently, tackling rudder loads with ease for crisp response.
• Quick Action: Achieves hard-over rudder movement in just 12 seconds, keeping maneuvers agile.
• Extended Reach: 7.87-inch stroke and 6.89-inch tiller arm compatibility suit a wide range of tiller and wheel systems.

Compatible with B&G AC-12 and NAC-2 course computers, it slips into existing setups from other brands too, minimizing retrofit hassles. Its aluminum construction withstands harsh marine environments, backed by IP67 water resistance and compliance with marine EMC standards.

How This Hydraulic Ram Enhances Your Autopilot

In autopilot mode, the course computer activates the clutch solenoid and spins the bidirectional motor to extend or retract the ram smoothly. When disengaged, it follows your manual inputs freely, protecting the system from shocks like rudder hits or groundings via built-in relief valves. Low average draw—around 1.3A at cruising—means it sips power from your 12V bank, leaving more for lights, nav gear, and comforts.

Pro tip for sizing: Always factor in your boat’s loaded displacement. A 20% bump from full tanks can push limits, so err toward overcapacity. This T0 ram shines on sailboats and powerboats with back-drivable steering, delivering up to 136 ft-lbs of rudder torque without drama.

Detailed Technical Specifications

Use mineral-based hydraulic fluid like ISO VG10-40 for longevity. Red lead extends, black retracts—simple polarity swap for direction.

Longevity and Care Tips

Keep it thriving with periodic fluid checks and clutch inspections. Its sealed design cuts maintenance, but mounting securely on a flat surface ensures vibration-free operation. Pairs beautifully with B&G sailing instruments for wind-aware steering that anticipates gusts.
