Equip your substantial vessel with the unyielding precision of the Raymarine Type 3 24V hydraulic linear drive. Engineered for mechanically steered boats exceeding 20,000 kg displacement—up to a robust 35,000 kg—this remanufactured powerhouse delivers seamless autopilot performance where electric drives fall short. Its self-contained design integrates a high-capacity reversing pump, fluid reservoir, and heavy-duty hydraulic ram, ensuring reliable steering even in demanding offshore conditions.
Connect it effortlessly to your rudder stock through an independent tiller arm, and harness the full potential of Raymarine's advanced autopilot systems. Ideal for long-range cruisers, commercial workboats, or superyacht tenders, this drive transforms helm control into effortless automation, letting you focus on the horizon ahead.
For vessels in this displacement class, hydraulic drives like this one outperform electric rams by providing consistent torque regardless of load or sea state. No stalling under windage or current—pure, proportional power directly from the pump ensures your autopilot tracks flawlessly during beam seas or quartering waves.
| Specification | Detail |
|---|---|
| Maximum boat displacement | 35,000 kg |
| Peak thrust | 1,200 kg |
| Maximum stroke | 300 mm |
| Hard-over to hard-over times | 10 seconds |
| Maximum rudder torque | 3,200 Nm |
| Corepack compatibility | ACU-400 |
Note: Requires a back-drivable steering system. Accessory tiller arm fittings may be needed from your helm manufacturer.
Mount the unit securely near the rudder stock, ensuring clear access for hydraulic lines and electrical connections. Plumb the system with high-pressure hoses rated for marine use, and prime the reservoir to eliminate air pockets before commissioning. Calibrate via your Raymarine autopilot interface for optimal rudder response—adjust gain settings to suit your hull's handling characteristics.
It's designed for mechanically steered vessels from over 20,000 kg up to 35,000 kg displacement, perfect for larger cruisers and workboats needing robust autopilot steering.
Remanufactured units are fully disassembled, inspected, and rebuilt with genuine parts to meet or exceed factory specs, offering the same performance and warranty eligibility at reduced environmental impact.
It integrates with the Raymarine ACU-400 corepack, which handles power distribution and control signals for seamless autopilot operation.
Yes, the 1,200 kg peak thrust and 3,200 Nm torque provide the muscle to maintain rudder control against high loads from waves, wind, or current.
While experienced boatbuilders can handle it, professional marine technicians ensure proper hydraulic plumbing, alignment, and calibration to avoid common pitfalls like air locks.
Check fluid levels every six months, inspect hoses for wear, and bleed the system annually. Use only specified hydraulic fluid to maintain peak efficiency.
Absolutely—via the ACU-400, it supports all Evolution series features like adaptive steering and fishfinding integration for comprehensive vessel control.
