Autopilot L/STROKE LIN DRIVE MODULE

Product N005 is a replacement motor module for Raymarine linear long-stroke autopilot rams. It is not the complete ram, but the drive unit (motor and gearbox) that allows you to refurbish your existing installation without replacing the entire mechanical arm.

No, this module is specifically designed as a spare part for Raymarine long-stroke linear actuators (Long Stroke), typically Type 2 models. It is not compatible with Type 1 or Type 3 actuators, hydraulic actuators, or wheelpilots.

Replacing this module is an intermediate-level operation. It requires basic mechanical and marine electrical skills. If you are not comfortable with disassembling parts and handling electrical connections on your boat, it is recommended to have a qualified technician perform the work.

Replacing only the motor module is a more economical and faster solution. This allows you to keep the existing mechanical arm and mounts on your boat, avoiding complex disassembly and a higher purchase cost for a complete actuator.

This module is suitable if your sailboat is equipped with a Raymarine Type 2 long-stroke linear actuator. These systems are typically installed on sailboats with a displacement of up to 20,000 kg. You must check the reference of your current actuator to confirm compatibility.

Yes, absolutely. After replacing the drive unit, a full commissioning and calibration procedure for the autopilot is mandatory. This includes dockside adjustments (Dockside Wizard) and sea trials to ensure optimal performance and maximum safety.

The N005 long-stroke linear drive module weighs approximately 1.786 kg.

Yes, this is an official spare part manufactured by Raymarine. Using an original part ensures perfect compatibility, maintains the performance of your autopilot, and extends the lifespan of your installation.

Common symptoms of a faulty module include:

The motor no longer turns despite the system being powered. Abnormal mechanical noises (squeaking, clunking) from the ram. Unusual slowness or weakness in rudder movements.The autopilot disengages while displaying a motor-related error or an overcurrent fault.

No, this module is designed to operate exclusively within the Raymarine ecosystem. It must be connected to a compatible Raymarine autopilot computer (such as the ACU-400) capable of supplying the power required for a Type 2 linear actuator.

To replace the module, you will likely need a set of standard wrenches, screwdrivers, and potentially a crimping tool and connectors for the power cables. It is advisable to refer to the installation manual of the complete linear actuator for specific details.

Yes, as a component of an autopilot system installed below deck, this module is designed to withstand the humidity and typical saltwater environment of a boat. It is crucial to ensure that all connections and seals are properly installed to maintain its watertight integrity.

Yes, absolutely. Before any work on the autopilot system, you must cut the power at the corresponding circuit breaker or switch to avoid any risk of short-circuit or injury.

No, this is not a complete autopilot system. The N005 is only a spare part: the drive motor module for an existing linear actuator. For a complete system, you also need a control unit (ACU), a rudder angle sensor, a compass, and a control head.

The best way to identify your model is to look for a label or identification plate directly on the cylinder body. Long-stroke cylinders have a longer piston stroke than standard models. The complete cylinder part number (for example M81132 for the Type 2 Long Stroke) will confirm compatibility.

This module is designed to require no maintenance. However, it is recommended to periodically check the condition of electrical connections to ensure they are clean and free of corrosion, and to visually inspect the module for any signs of water ingress.

This module is the "muscle" of the autopilot. It receives the electrical commands from the computer (ACU) and converts them into powerful mechanical movement to push or pull the ram arm, which in turn actuates the boat's rudder to maintain heading.

No, this module is specifically for the long-course version. Even if the motor may appear similar, the gears and internal settings can differ. To ensure safety and performance, it is essential to use the exact part corresponding to your actuator model.

The module is usually supplied with its own short power cables. You will need to connect these to your boat’s existing wiring leading to the autopilot computer. Ensure connections are secure, watertight, and of correct polarity.

By replacing a worn or faulty module with this new part, you will restore your autopilot’s original performance. You will regain the system’s initial speed, power, and responsiveness, resulting in improved course-keeping and optimized power consumption.
