Imagine gliding across the water with precise speed data at your fingertips, helping you optimize your sail trim or throttle control without guesswork. The Raymarine i50 Speed Display System, paired with its reliable nylon thru-hull transducer, delivers exactly that for serious boaters. Whether you’re racing competitively, cruising leisurely, or navigating challenging waters, this instrument provides essential real-time insights into your vessel’s performance through water speed, GPS-referenced speed over ground (SOG), velocity made good (VMG), and more.
Crafted for the demands of marine environments, it stands out with oversized, high-contrast digits that remain legible even in bright sunlight or pitch-black nights, thanks to intuitive red backlighting. Boaters appreciate its seamless integration into helm setups, blending rugged durability with a sleek, modern aesthetic that matches Raymarine’s multifunction displays.
Why Boat Owners Rely on the i50 Speed Display
Comprehensive Speed Metrics: Track boat speed through water for true hydrodynamic performance, SOG for navigation efficiency, VMG to fine-tune racing tactics, average and maximum speeds, trip/distance logs, and sea surface temperature—all on one intuitive screen.
Effortless Visibility: Extra-large LCD digits cut through glare and darkness, with adjustable red backlighting that preserves night vision while highlighting critical data.
Versatile Networking: SeaTalkng ready out of the box, with easy adaptation to NMEA2000 or legacy SeaTalk systems. Use it as a master unit with its dedicated transducer or as a repeater pulling data from your network.
Marine-Tough Build: IPX6 waterproof rating shrugs off heavy spray, waves, and washdowns. Compact dimensions (about 4.22″ wide x 4.52″ high x 1.7″ deep) fit neatly on any dash via surface or optional trunnion mount.
Efficient Operation: Draws minimal power (under 1W as repeater, up to 2.4W with transducer), ideal for battery-conscious setups on sailboats, powerboats, yachts, or RIBs.
Unlock Deeper Insights for Better Boating
Speed isn’t just a number—it’s your edge on the water. For racers, VMG reveals how effectively you’re pointing toward the mark, letting you adjust sails on the fly. Cruisers use trip logs and temperature readings to plan fuel-efficient routes or spot productive fishing grounds. The nylon thru-hull transducer ensures accurate water speed by mounting flush below the waterline, minimizing drag and turbulence interference compared to paddlewheel alternatives.
Simple keypad controls let you toggle between displays—like countdown race timers or log resets—without distraction. Group dimming syncs brightness across multiple i50 units or Raymarine autopilots, creating a cohesive cockpit experience.
Simple Setup for Professional Results
Installing the i50 Speed is straightforward for DIYers or pros. The thru-hull transducer requires a clean hull hole (typically 2-inch diameter), sealed with marine sealant for a watertight fit. Connect the transducer directly to the display, then link via SeaTalkng cables to your network—spur connectors make daisy-chaining effortless. Power it from 12V DC (10-16V range), and calibrate speed via on-screen prompts for hull-specific accuracy.
Pro tip: Position the display at eye level, avoiding direct sun to maximize backlight efficiency. Its front-mount design eliminates rear access hassles, and the included sun cover protects against UV fade during storage.
Seamless Fit in Your Marine Ecosystem
Expand your setup with i50 Depth or Tridata for all-in-one monitoring, or pair with i70 color instruments for graphical trends. It plays nicely with Raymarine autopilots (like p70 series) and MFDs (aXS, C, E, Axiom lines), sharing data for automated responses to speed changes. Legacy ST60+ owners love the identical footprint for drop-in upgrades.
“Switched to i50 Speed from an older analog gauge—night-and-day difference in readability and network smarts. Perfect for my J/105 racer.”

Keep It Running Flawlessly
Regular transducer cleaning prevents marine growth buildup, ensuring precise readings. Wipe the display with freshwater after saltwater exposure, and store in a dry helm during off-seasons. Low power draw means less battery worry, but monitor connections for corrosion in humid climates.
