Raymarine Type 1 Rotary Drive - 12V

Enhance Your Vessel's Steering with Reliable Autopilot Performance

Imagine effortless navigation on open waters, where your autopilot handles the helm with precision and minimal noise. The Raymarine Type 1 Rotary Drive in 12V configuration delivers exactly that for powerboats and sailboats equipped with chain-and-sprocket steering systems. Ideal for cable or rod setups, this drive unit transforms manual steering into seamless, automated control, allowing you to focus on the journey ahead.

Crafted for vessels up to 11,000 kg displacement, it combines robust torque with efficient power use, ensuring reliable operation even in demanding conditions. Boat owners appreciate its whisper-quiet performance, which preserves the tranquility of your onboard experience without compromising on strength.

Key Specifications That Matter on the Water

Built to meet the rigors of marine environments, this rotary drive stands out with specs tailored for real-world boating:

• Drive Configuration: Type 1 Rotary – perfect for helm-driven systems via chain and sprocket.
• Power Supply: 12V DC, with efficient consumption between 24-48W to extend battery life during long passages.
• Peak Torque: 20 Nm for confident handling of your boat's displacement.
• Shaft Speed: Up to 33 RPM, enabling quick response times.
• Hard-Over Time: Approximately 10 seconds under no-load conditions for agile maneuvers.
• Maximum Vessel Capacity: Supports boats up to 11,000 kg (around 24,000 lbs), making it suitable for mid-sized craft.

These specs aren't just numbers—they translate to smoother tracking, reduced wear on steering components, and enhanced safety during autopilot engagement.

Why Rotary Drives Excel in Chain-and-Sprocket Setups

Unlike linear drives that push or pull directly on the rudder, rotary units engage through your existing helm chain, preserving the mechanical familiarity of your setup. This design minimizes modifications, often requiring only sprocket adaptations for a perfect fit. The result? Powerful steering that feels natural, with torque delivered directly where it's needed most.

For sailors and powerboaters, this means better integration with traditional steering, quieter operation compared to hydraulic alternatives, and lower maintenance demands. It's a smart upgrade for boats where space is at a premium or when retrofitting older systems.

Seamless Integration and Compatibility

Pair this drive with the ACU-200 autopilot control unit for plug-and-play compatibility within Raymarine's ecosystem. Whether you're running an Evolution series pilot or expanding an existing setup, it slots in effortlessly. Marine enthusiasts often highlight how this combo delivers responsive course-holding, even in choppy seas or following seas.

Pro tip: Before installation, assess your chain sprocket alignment—small tweaks here can optimize torque transfer and longevity.

Performance Benefits for Everyday Boating

Users rave about the drive's ability to maintain steady headings while freeing up crew for sail trim or fishing. Its quiet hum fades into the background, unlike noisier competitors, and the efficient power draw suits extended offshore trips. Over time, this reliability reduces fatigue from constant manual corrections, making every outing more enjoyable.

In practical terms, expect improved fuel efficiency from precise steering and less deviation from your plotted course—key for long-distance cruisers.

Maintenance Tips for Long-Term Reliability

To keep your rotary drive performing at peak:

• Inspect chain and sprockets seasonally for wear or slack.
• Rinse with fresh water after saltwater exposure to prevent corrosion.
• Monitor electrical connections for secure, clean contacts.
• Test autopilot functions regularly in calm conditions to catch issues early.

With proper care, this unit delivers years of dependable service, backed by Raymarine's commitment to quality.
