Detailed description

Designed for demanding hydraulic steering systems, the Raymarine Type 3 hydraulic linear actuator (M81202) is an autopilot drive solution operating at 12V. This model is intended for vessels requiring higher thrust force, placing it above Type 2 versions such as the E12207 (12V) or E12208 (24V), and providing a 12V alternative to the M81203 (Type 3 24V) model.

Integration and technical performance

The M81202 actuator integrates with the autopilot system via a compatible Raymarine route computer. Installation requires a very robust mounting structure capable of withstanding the peak thrust levels generated by the unit, in accordance with technical specifications. The installation process includes precise alignment of the hydraulic actuator, connection to the steering system, mounting of the hydraulic pump and reservoir, and electrical connections for the clutch and route computer.

With a main length of 452 mm, the actuator has specific dimensions for integration, including mounting points and offsets such as 76 mm, 101 mm, 55 mm, 50 mm, 20 mm, 9 mm, 51 mm, 90 mm, 108 mm, 171 mm, and 102 mm (all dimensions in millimeters). For safety and maintenance, it features a quick-release tab allowing manual release of the actuator from the tiller arm or quadrant in case of failure. Raymarine equipment complies with electromagnetic compatibility (EMC) regulations for the recreational marine environment, ensuring reliable integration aboard.

Expert opinion

« Technical analysis: Raymarine Type 3 12V linear hydraulic ram »

The Raymarine M81202 Type 3 linear hydraulic ram is a critical component for vessels equipped with hydraulic steering systems requiring a robust autopilot. This 12V model is particularly suitable for medium to large boats that need significant thrust capacity, exceeding that of Type 2 rams, to handle heavier rudder loads.

Its selection is justified when steering power and responsiveness are essential for course-keeping. Installation of this ram demands careful attention to the boat’s structural rigidity, as the unit generates substantial forces. It is imperative to ensure the mounting point and tiller arm or quadrant are dimensioned to withstand these stresses. Absolute cleanliness of the hydraulic circuit is also critical during integration to guarantee proper valve operation.

Compared to the M81203 model, which operates on 24V, the M81202 delivers the same Type 3 thrust capacity for 12V installations, eliminating the need for a converter or secondary electrical system. The inclusion of a quick-release tab is a practical feature, allowing manual steering recovery in emergencies or for maintenance. This ram is obviously not suitable for cable or mechanical steering systems. It is designed for professional integration into an existing Raymarine autopilot system.

Frequently Asked Questions

Need help? Contact us

Which Raymarine route computers is this linear actuator compatible with?

The Raymarine Type 3 linear hydraulic actuator (M81202) is designed to integrate with a compatible Raymarine route computer. For successful integration, it is recommended to consult the installation manuals for the SPX systems (reference 87072) and the SPX commissioning manual (reference 81287), as well as the SeaTalkng reference manual (reference 81300).

What is the required supply voltage for the M81202 actuator?

This Raymarine Type 3 linear hydraulic actuator (M81202) requires a 12V power supply to operate.

What structural strength is required for the mounting bracket of this hydraulic ram?

Installation of the Type 3 (M81202) linear hydraulic ram requires a very robust mounting structure. It must be securely fastened to a substantial element of your vessel's frame. The mounting structure, as well as the tiller arm or quadrant, must be capable of withstanding the peak thrust levels generated by the unit.

Could you provide the exact dimensions of the Raymarine Type 3 linear hydraulic actuator (M81202)?

The main length of the Raymarine Type 3 (M81202) hydraulic linear actuator is 452 mm. Other key installation dimensions include offsets of 76 mm, 101 mm, 55 mm, 50 mm, 20 mm, 9 mm, 51 mm, 90 mm, 108 mm, 171 mm and 102 mm. All measurements are given in millimetres.

How to use the quick-release tab on the hydraulic ram when needed?

The Raymarine Type 3 (M81202) linear hydraulic ram is equipped with a quick-release tab. In case of a situation requiring manual release, simply pull the red tab to disengage the R clip, then lift the drive unit to release it from the tiller arm or quadrant.

Does this product comply with electromagnetic compatibility standards for the marine environment?

Yes, the Type 3 (M81202) hydraulic linear actuator and Raymarine accessories comply with electromagnetic compatibility (EMC) regulations applicable to recreational marine environments. Correct installation is crucial to maintain this EMC performance.

What additional components are required for a complete installation of this hydraulic cylinder?

For a complete and functional installation of this linear hydraulic cylinder, you will need a hydraulic pump, a reservoir, and a Raymarine route computer compatible with your system. The installation will also include the electrical connections for the clutch and the route computer.

Why is cleanliness so critical when installing a hydraulic system?

Absolute cleanliness is essential during installation and handling of hydraulic systems. Even a tiny speck of dirt can prevent the system's check valves from functioning properly, potentially leading to reduced performance or oil leaks.
