Equip your vessel with precision marine instrumentation that stands up to the demands of serious boating. The Raymarine thru-hull speed transducer delivers accurate speed-over-water readings and water temperature data, essential for navigating challenging conditions, optimizing fuel efficiency, and enhancing your overall boating experience. Designed for seamless integration into Raymarine's ecosystem of chartplotters, multifunction displays, and instrument consoles, this retractable sensor ensures reliable performance whether you're cruising coastal waters or venturing into offshore territory.
What sets this transducer apart is its robust construction tailored for thru-hull mounting, allowing for a clean, unobtrusive installation that minimizes drag and maximizes accuracy. Unlike paddlewheel alternatives, its impeller-based design provides consistent data even at low speeds, helping skippers make informed decisions during docking, trolling, or high-speed runs.
Installing a thru-hull speed transducer requires careful planning, but this model's straightforward design makes it accessible for DIY enthusiasts and pros alike. Select a mounting location forward of the propellers, in a flat section of the hull, and at least 1/3 of the waterline length aft of the bow to avoid turbulence. Drill a precise hole matching the 1-inch thru-hull fitting, bed it with marine sealant, and secure the sensor. The retractable feature means you can test-fit before final commitment. Once wired to your Raymarine i50, i70, or Axiom series instruments, calibrate via the intuitive setup menu for tailored accuracy to your vessel's specifics.
Pro tip: Fair the sensor's trailing edge with epoxy filler to align it perfectly parallel to the waterline, optimizing flow over the impeller for the most reliable readings.
To keep your speed data trustworthy, perform seasonal maintenance: Remove the transducer, clean the impeller of marine growth with a soft brush and mild cleaner, and inspect seals for wear. In fouling-prone waters, pair it with anti-fouling paint on the sensor body. This transducer shines in tournament fishing scenarios, where precise speed control during drifts or live bait runs can make or break your day on the water. Its sensitivity to subtle changes supports advanced features like current correction when networked with GPS and compass data.
For bluewater adventurers, the temperature sensor helps monitor thermoclines, aiding in baitfish location and big-game pursuits. Integrated with Raymarine's SeaTalk or NMEA 0183 networks, it populates your MFD with layered intel, from SOG comparisons to log trip distances.
It features a thru-hull mount, ideal for permanent installations below the waterline, with support for hull deadrise angles from 0 to 22 degrees.
Yes, it provides both speed-over-water and water temperature readings through an integrated thermistor, perfect for navigation and fishing applications.
The cable measures 45 feet, offering ample length for routing to instruments in various boat layouts.
Absolutely, its retractable piston design allows you to withdraw it completely through the hull, protecting it during storage or trailering.
It works seamlessly with Raymarine instruments like the i40/i50/i70 series, STng networks, and multifunction displays such as Axiom and Element models.
Clean the impeller regularly with a soft brush to remove growth, and check seals annually to ensure watertight integrity.
Yes, built with bronze and rugged composites, it's proven in harsh marine environments, delivering reliable data even in heavy seas.
