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.
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.
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.

Use mineral-based hydraulic fluid like ISO VG10-40 for longevity. Red lead extends, black retracts—simple polarity swap for direction.
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.
It's optimized for vessels up to 19,000 lbs (9,000 kg) fully laden, ideal for mid-sized sailboats and powerboats with tiller or mechanical steering.
Yes, it's compatible with many existing ram, rotary, or drive units from other manufacturers, as well as B&G AC-12 and NAC-2 computers.
The electromagnetic clutch disengages for free manual steering and engages via the course computer for autopilot control, with a low 12W coil draw.
Opt for ISO VG10 to VG40 hydraulic mineral fluids meeting ISO 6743-4 HV standards, such as compatible commercial options for smooth operation.
Internal relief valves protect against overloads from rudder strikes, grounding, or heavy weather, enhancing durability.
Efficient at 1.3A average during cruising (25% duty), peaking at 14A intermittently, making it battery-friendly for extended voyages.
Flexible mounting with specific wiring for extension/retraction; consult setup guides for optimal positioning.
Hydraulic Ram to 12V
High power, efficient drive units for maximum power with minimum consumption. Ram drives allow the Power Steer mode on the Pilot to be used in cases of manual steering failure Fully Integrated (T0, T1 and T2 units) hydraulic system, no external hoses, reservoirs etc. Always remember to use the fully laden displacement of your boat when selecting a pilot. Typically a yacht fully provisioned with the water and fuel tanks full can be as much as 20% above the designed displacement. If your boat falls between two pilot types, choose the larger pilot type - an under rated pilot may not be able to perform adequately when you need it most. If in doubt, please check with an authorized B & G Dealer. If you are using a Ram, Rotary drive or existing drive unit from another manufacturer, these will, in most cases, be compatible with B & G units.
