Octopus Autopilot Drives 7″ Stroke Remote 38mm Bore Linear Drive Review

Let’s Talk About Octopus Autopilot Drives 7″ Stroke Remote 38mm Bore Linear Drive

The Octopus Autopilot Drives 7″ Stroke Remote 38mm Bore Linear Drive offers a unique solution for boat owners seeking to integrate autopilot functionality with their existing mechanical steering systems. Manufactured by Octopus Autopilot Drives, this linear actuator promises ease of installation and simplified operation. Its design boasts mechanical simplicity, which appeals to offshore mariners looking for reliability and ease of service.

I’ve spent over a decade working with marine systems, and I’ve seen countless autopilot setups ranging from simple tiller pilots to complex hydraulic steering integrations. My challenge has always been finding robust, reliable solutions for vessels with mechanical steering, without requiring a complete system overhaul. The allure of the Octopus Autopilot Drive was its promise of a direct, relatively painless integration.

Upon unboxing, the Octopus Autopilot Drive struck me as a solidly built unit. Its weight suggested robust construction, and the black finish appeared durable. The compact design was a welcome surprise, indicating that it wouldn’t require significant modification to fit within the confined spaces typical of a boat’s steering compartment.

Compared to other linear drive systems I’ve worked with, like the Raymarine Type 1 linear drive or the Simrad DD15 drive unit, the Octopus Autopilot Drive seemed simpler in its overall design. I chose it over the others due to its stated ease of installation for mechanically steered boats and the fact that it’s shipped pre-filled with hydraulic oil, eliminating a potentially messy step. My initial excitement was tempered by a bit of skepticism, as “simple” doesn’t always equate to “effective” in the marine environment, but I was eager to see it in action.

Real-World Testing: Putting Octopus Autopilot Drives 7″ Stroke Remote 38mm Bore Linear Drive to the Test

First Use Experience

My initial testing of the Octopus Autopilot Drive took place on a 36-foot sailboat with a traditional tiller steering system. The installation process, as advertised, was relatively straightforward, requiring primarily mechanical connections to the tiller arm. I tested it in calm bay conditions initially to assess basic functionality.

The system performed admirably in calm waters, maintaining a steady course with minimal deviation. However, as the wind picked up and the seas grew choppier, the unit began to struggle slightly, exhibiting some overshoot in its course corrections. The ease of use was definitely a plus; the autopilot engaged and disengaged smoothly, and the manual override function worked flawlessly.

Extended Use & Reliability

After several weeks of consistent use, including a coastal passage with varying sea states, the Octopus Autopilot Drive has proven to be generally reliable. There haven’t been any catastrophic failures, and the unit continues to function, albeit with some limitations. A slight hydraulic oil leak developed near one of the cylinder fittings after about 50 hours of use, requiring a minor tightening.

Despite the leak, the unit continues to function, but it underscores the need for regular inspection and maintenance. Cleaning is relatively easy due to its simple design, but access to the mounting bolts for inspection and tightening can be challenging depending on the installation location. While it hasn’t completely outperformed expectations, it offers a good balance of ease of use and basic functionality compared to previous simpler windvane steering systems I’ve used on similar vessels.

Breaking Down the Features of Octopus Autopilot Drives 7″ Stroke Remote 38mm Bore Linear Drive

Specifications

The Octopus Autopilot Drives 7″ Stroke Remote 38mm Bore Linear Drive boasts several key technical specifications:

• Stroke Length: 7 inches provides adequate rudder movement for boats within a specific size range. This dictates how far the ram can extend and retract, affecting the degree of rudder angle achievable.
• Bore Size: The 38mm bore relates to the diameter of the hydraulic cylinder and impacts the force it can exert. A larger bore generally translates to more power but also requires a larger pump.
• Hydraulic Actuation: Uses hydraulic fluid to transmit force from the pump to the rudder. This offers a smooth and powerful steering action.
• Reversing Pump: An Octopus reversing pump allows for bidirectional movement of the hydraulic cylinder. This is crucial for controlling the rudder’s direction.
• Solenoid Valve: A solenoid valve locks the cylinder when the autopilot is engaged. This prevents manual steering from interfering with the autopilot’s control.
• Oil Reservoir: A translucent oil reservoir allows for easy visual inspection of the hydraulic fluid level. This simplifies maintenance and prevents low-fluid damage.

These specifications are critical because they dictate the unit’s suitability for a given vessel and its ability to handle varying sea conditions. The stroke length must be appropriate for the rudder size, while the bore size determines the steering force available.

Performance & Functionality

The Octopus Autopilot Drive performs its core function of maintaining a set course reasonably well in moderate conditions. Its strengths lie in its simplicity and ease of integration. The unit is straightforward to install and operate, even for boat owners with limited technical expertise.

However, its weaknesses become apparent in more challenging conditions. In heavy seas or strong winds, the autopilot can struggle to maintain a precise course, exhibiting some hunting and overcorrection. While it meets basic expectations for a mechanically steered vessel, it doesn’t offer the same level of performance as a dedicated hydraulic steering system.

Design & Ergonomics

The build quality of the Octopus Autopilot Drive is generally good, with robust materials used throughout. Its weight suggests a solid construction that can withstand the harsh marine environment. The unit is relatively compact, making it easier to install in confined spaces.

The user-friendliness is a definite advantage. The translucent oil reservoir is a thoughtful touch, simplifying fluid level checks. However, the location of the mounting bolts can make access for maintenance a bit challenging depending on the specific installation.

Durability & Maintenance

The long-term durability of the Octopus Autopilot Drive remains to be seen, but initial impressions suggest it should last for several years with proper maintenance. The hydraulic oil leak I experienced after a relatively short period underscores the importance of regular inspections and tightening of fittings. Easy access to components would simplify maintenance.

Accessories and Customization Options

The Octopus Autopilot Drive typically comes as a standalone unit, with minimal included accessories beyond basic mounting hardware. Customization options are somewhat limited, primarily revolving around integrating it with different autopilot control heads and rudder feedback sensors.

While it’s not specifically designed to be compatible with accessories from other brands, standard hydraulic fittings and electrical connections allow for some degree of flexibility in integrating it with existing systems. However, it’s crucial to ensure compatibility before attempting any modifications.

Who Should Buy Octopus Autopilot Drives 7″ Stroke Remote 38mm Bore Linear Drive?

The Octopus Autopilot Drives 7″ Stroke Remote 38mm Bore Linear Drive is perfect for boat owners with mechanically steered vessels seeking a relatively simple and cost-effective autopilot solution. It’s especially well-suited for coastal cruisers and weekend sailors who prioritize ease of use and integration over ultimate performance in extreme conditions. This is a good fit for someone not looking to spend a fortune but needs a basic autopilot solution.

Those who should skip this product are offshore sailors or those who frequently encounter heavy seas or strong winds. These boaters would likely benefit from a more robust and powerful hydraulic steering system with a dedicated autopilot drive. Also, those unwilling to perform routine maintenance should look elsewhere.

A must-have accessory would be a high-quality autopilot control head with advanced features like wind steering and route planning.
