Raymarine

<h3>Raymarine: Decades of Innovation on the Water</h3><p>For more than 80 years, <strong>Raymarine</strong> has been one of the most trusted names in marine electronics, serving recreational boaters, anglers, and light commercial mariners around the world. Born from a legacy of precision engineering, Raymarine designs products purpose-built to endure the punishing demands of the marine environment — from saltwater spray and UV exposure to the vibration and shock of open-water passages. Today, the brand maintains a global presence across 12 countries and continues to push the boundaries of what&apos;s possible on the water.</p><p>At the heart of the Raymarine lineup is an expansive range of marine electronics that covers nearly every navigation and situational awareness need a boater could have. Whether you&apos;re weekend cruising on a bay, trolling offshore for big game fish, or delivering a vessel across an ocean, Raymarine has purpose-engineered technology to help you do it more safely and confidently.</p><h3>Radar, Autopilots &amp; Intelligent Navigation</h3><p>Raymarine has long been a standard-setter in radars and autopilots. Their Quantum and Cyclone radar series bring CHIRP pulse compression technology and solid-state architecture to both weekend sailors and serious offshore mariners. Raymarine autopilots — spanning the Evolution and Axiom Auto series — integrate seamlessly with onboard navigation systems and use intelligent algorithms to maintain course with minimal helm input, reducing fatigue on long passages. Together, these systems represent some of the most sophisticated navigation assistance available to the recreational market.</p><h3>Multi-Function Displays: The Heart of the Helm</h3><p>Raymarine&apos;s multi-function display systems serve as the central hub of any modern helm setup. The Axiom and Axiom Pro MFD series offer responsive touchscreens, integrated RealVision 3D sonar, and compatibility with Navionics and LightHouse charts. These displays are engineered to network effortlessly with other Raymarine devices, giving captains a unified, at-a-glance view of navigation, fishfinding, radar, and vessel data — all from a single screen.</p><h3>Wind Speed Instruments &amp; Marine Data</h3><p>Precise environmental data is critical for sailors and performance-focused boaters alike. Raymarine&apos;s <a href="/201187-wind-speed-indicators-raymarine-11286">wind speed indicators</a> and instrument systems deliver real-time data on apparent and true wind speed, direction, depth, speed through water, and more. Engineered to integrate with the broader Raymarine network, these instruments feed data directly into autopilots and chart plotters for a fully connected onboard experience.</p><h3>Accessories &amp; Replacement Parts</h3><p>Keeping your Raymarine system running at its best is straightforward thanks to a broad selection of <a href="/11286-raymarine-electronics-parts-accessories-200363">electronics parts and accessories</a>. From transducer cables and mounting brackets to network cables, power harnesses, and display covers, Raymarine offers the components needed to install, expand, or maintain any part of your onboard electronics suite. These accessories are built to the same marine-grade standards as Raymarine&apos;s primary products.</p><h3>Why Boaters Choose Raymarine</h3><ul style="list-style:disc"><li><strong>Proven durability</strong> — designed and tested for real-world marine conditions</li><li><strong>Seamless integration</strong> — all Raymarine products network via SeaTalkng and NMEA 2000</li><li><strong>Intuitive interfaces</strong> — touchscreen and keypad controls suited to any sea state</li><li><strong>Global support</strong> — backed by a worldwide dealer and service network</li><li><strong>Continuous innovation</strong> — regular firmware and feature updates extend product lifespan</li></ul>

Product Details

The Raymarine M81121 Type 2 Hydraulic Reversing Pump is a professional-grade autopilot drive unit designed for boats with hydraulic steering systems. This 12-volt pump interfaces directly with your vessel's steering system to provide precise autopilot control, working seamlessly with Raymarine Evolution autopilot systems and ACU-400 actuator control units.

Key Features:

  • Compatible with hydraulic steering systems equipped with 9.8-21 cubic inch (160-350cc) hydraulic steering rams
  • 12-volt DC operation with maximum stall pressure of 1450 PSI
  • Peak flow rate of 122 cubic inches minimum (no load)
  • Rugged reversing hydraulic pump design for reliable performance
  • Works with Raymarine 400 Series and S3 Series corepacks
  • Compatible with Raymarine SmartPilot and Evolution autopilot systems

This Type 2 pump is specifically matched to the ram capacity of mid-sized hydraulic steering systems, making it ideal for boats with cylinder rams mounted to the rudder on inboard engine boats or to the drive unit on outboard engine boats. To ensure proper compatibility, verify the size of your hydraulic cylinder ram(s) matches the 160-350cc (9.8-21 cubic inch) capacity range before ordering.

The M81121 delivers the precision steering control needed for extended cruising, offshore passages, and fishing trips, allowing you to maintain course while reducing fatigue on long runs.
