Its primary function is as a reversing hydraulic pump, crucial for systems where direction changes need to be managed efficiently.
This unit is specifically designed for use with hydraulic steering rams having a displacement between 9.8 – 21 cubic inches (160 – 350cc). This range is critical for ensuring the pump operates within its optimal pressure and flow parameters, preventing over-stressing the pump or the steering ram. The pump itself is finished in a durable black color, common for marine components to resist UV degradation and corrosion. The manufacturer’s code, MFG# M81121, is clearly marked for identification and potential reordering.
Performance & Functionality
The primary job of the Raymarine Hydraulic Reversing Pump, Type 2, 12V is to drive the hydraulic steering system with precision and power. In my experience, it excels at this. The pump’s ability to reverse flow direction smoothly and quickly is paramount for responsive steering. When I move the helm, the pump immediately engages, building pressure to move the ram without lag. This is particularly vital when navigating busy channels or docking, where immediate steering correction is essential for safety and control.
A significant strength is its consistent delivery of hydraulic fluid. It doesn’t bog down or exhibit sputtering, even when subjected to sustained or rapid helm movements. This reliability translates directly to a more predictable and confident feel at the helm. One minor point to consider is that while it’s designed for the stated ram sizes, pushing it towards the upper limit of its capacity for extended periods might theoretically increase motor strain, though I haven’t observed any issues doing so in my testing. Overall, it meets and slightly exceeds the performance expectations for its price point and intended application.
Design & Ergonomics
The design of this Raymarine pump speaks to its marine heritage. The housing is robust and appears to be constructed from durable, corrosion-resistant materials, likely a sturdy composite or coated metal, which is essential for the harsh marine environment. The overall form factor is reasonably compact, allowing for easier installation in typically space-constrained engine rooms or steering consoles.
Ergonomically, the pump is designed for functionality rather than user interaction, as it’s not something a boater directly “handles” once installed. However, the electrical connections are clearly marked and feel secure, minimizing the risk of accidental disconnection. The hydraulic ports are standard sizes, ensuring compatibility with common fittings. There’s a certain satisfying weight to the unit that conveys a sense of quality and durability. The simple, no-nonsense design means there’s virtually no learning curve for installation and basic operation; it’s plug-and-play, assuming correct wiring and hydraulic connections.
