Ray E12207 Type 2 Reman Hydraulic Linear Drive 12v

Powering Precise Autopilot Performance for Heavy-Displacement Vessels

Navigating larger boats demands unwavering reliability from your autopilot system, especially on vessels pushing the limits of mechanical steering. This remanufactured hydraulic linear drive steps up as a robust solution, engineered to handle boats up to 22,000 kg with seamless precision. Its self-contained design integrates a high-efficiency reversing pump, ample reservoir, and powerful hydraulic ram, delivering responsive control that feels like an extension of your helm.

Boat owners upgrading older systems or seeking cost-effective replacements rave about its ability to maintain course in choppy seas or long passages. By linking directly to the rudder stock through a tiller arm, it ensures direct mechanical feedback, minimizing lag and maximizing safety during demanding maneuvers.

Engineered for Demanding Marine Conditions

What sets this drive apart is its balance of raw power and finesse. With peak thrust exceeding 585 kg and a maximum rudder torque of 1,270 Nm, it tackles heavy loads without hesitation. The 254 mm stroke allows for full rudder travel, while hard-over times clock in at just 10 seconds—ideal for quick responses in tight quarters or evasive actions.

• Displacement Mastery: Optimized for vessels over 20,000 kg, ensuring stability on displacement hulls and semi-planing craft.
• Back-Drive Compatibility: Works only with steering systems that allow back-driving, preserving the tactile feel of manual steering.
• Core Integration: Pairs flawlessly with the ACU-400 corepack for plug-and-play setup in Raymarine Evolution autopilots.

Remanufacturing breathes new life into these units through rigorous testing, component upgrades, and marine-grade seals, often outperforming new installs in real-world durability tests shared by offshore skippers.

Detailed Performance Specifications

Streamlined Installation Insights

Installing this drive unit transforms your autopilot setup without major overhauls. Mount it securely near the rudder post, ensuring the tiller arm aligns with your existing quadrant or arm. Accessory brackets from steering makers like Jefa or Octopus often bridge any gaps seamlessly.

1. Verify back-drive capability on your hydraulic or cable steering—essential for autopilot feedback.
2. Secure hydraulic connections with bleed valves to purge air, preventing spongy response.
3. Integrate with ACU-400 for 12V power draw, calibrating via SeaTalk NG for vessel-specific tuning.
4. Test in calm waters: Full lock-to-lock sweeps confirm 10-second cycles before offshore runs.

Pro tip from seasoned installers: Position the reservoir high to avoid cavitation in heeled states, extending service life on long voyages.

Long-Term Reliability and Maintenance

Remanufactured units like this one undergo factory-level refurbishment, replacing seals, fluid, and pumps to meet or exceed OEM standards. Regular checks—fluid levels every season, filter swaps annually—keep it humming through thousands of sea miles.

Owners report fewer hydraulic leaks compared to aged originals, thanks to upgraded O-rings resistant to ethanol-blended marine fluids. Pair it with a backup battery for uninterrupted performance during electrical gremlins.
