The drive unit performed admirably in calm to moderate conditions, maintaining a steady course with minimal deviation, even when I intentionally put it through its paces with some minor course changes.
During the test, I encountered a brief period of choppy seas and increased wind, conditions that would typically tax a weaker drive unit. This particular model held its own, demonstrating impressive torque and a consistent response to the autopilot’s commands. There were no unusual noises, excessive heat, or hesitation in its movement, which immediately put my mind at ease. Its 12 inch stroke allowed for ample rudder travel, and the 1050 lbs of thrust was more than sufficient for the rudder loads encountered.
Extended Use & Reliability
After several weeks and hundreds of nautical miles logged with this drive unit consistently engaged, its performance has remained impressively stable. It’s become an integral, almost invisible, part of the vessel’s operation, reliably handling steering duties for hours on end. I’ve experienced everything from slow, deliberate course corrections in light winds to rapid adjustments during squalls, and the drive has responded with consistent precision.
Durability seems to be a strong suit. Despite constant exposure to salt spray, varying humidity, and the relentless vibration of offshore sailing, there are no visible signs of degradation. The black casing shows minor scuffs from installation, but the unit itself remains free of rust or corrosion. Maintenance has been minimal; a simple rinse with fresh water after a long run and a periodic check of connections are all that’s been required. Compared to some older, less robust drive units I’ve worked with in the past, this Raymarine component feels significantly more robust and built to last. It certainly outperforms those budget alternatives that start groaning or becoming sluggish after just a few seasons.
Breaking Down the Features of Raymarine Short Linear Drive, Type 2, 12V
Specifications
This auto-pilot drive unit boasts several key specifications that define its capability. Its core function is powered by a 12 Volt system, making it compatible with most common marine electrical setups. It’s designed for vessels up to a substantial 33,000 lbs, which covers a wide range of cruising sailboats and motor yachts.
The 12 inch stroke is a critical dimension, determining the range of rudder movement it can achieve. This is complemented by an impressive 1050 lbs of thrust, indicating its strength in moving the rudder against water resistance. In terms of physical size, it measures approximately 7.8 inches high by 4.5 inches wide, with a length of 27.5 inches at mid-stroke, a reasonably compact footprint for its power.
These specifications translate directly into practical performance. The ample stroke allows for precise control over rudder angle, crucial for fine-tuning course holding and maneuverability. The high thrust capability ensures that even larger rudder stocks can be moved effectively, providing confidence in challenging conditions. The 12V operation means integration into existing power systems is typically straightforward, avoiding the need for complex voltage converters.
Performance & Functionality
The primary job of the Raymarine Short Linear Drive, Type 2, 12V is to translate electronic steering commands into physical rudder movement, and it excels at this. Its main strength lies in its consistent and responsive performance; it moves smoothly and accurately, providing the autopilot with the precise feedback it needs to maintain a course. I found its operation to be virtually silent, a welcome change from the often-noisy mechanisms of older systems.
A key performance aspect is its ability to handle varying loads without complaint. Whether it was holding a precise course in a steady breeze or fighting a strong cross-current, the drive maintained its position and executed commands faithfully. Its robustness means it doesn’t falter under pressure.
The main weakness, if one can call it that, is the unit’s weight and size. While compact for its power, it’s still a substantial piece of hardware that requires solid mounting points. For smaller vessels with very limited space, careful consideration of its dimensions would be necessary.
Design & Ergonomics
The design of this linear drive unit is all about function and marine-grade robustness.
