Navico Temperature Sensor Thru-Hull — Product description

HS-WS-SS Mtg Kit - Mounting kit for transom mount 83/200 kHz skimmer Transducers

Enhance your boating adventures with precise water temperature readings right from your multifunction display. This thru-hull sensor connects effortlessly to your NMEA 2000 network, delivering real-time data that helps anglers target the perfect fishing spots and boaters monitor environmental conditions. Whether you're tracking surface water changes or adapting to varying hull setups, it provides reliable insights without guesswork.

Why Water Temperature Monitoring Elevates Your On-Water Experience

Water temperature influences everything from fish behavior to engine performance and safety. Warmer waters might signal active striper migrations, while cooler depths could hide trophy bass. Installed through your hull, this sensor captures bottom-line readings unaffected by surface foam or engine wash, giving you an edge in competitive fishing or leisurely cruises. Boaters use it to avoid hypothermia risks in live wells or optimize bait storage by watching fridge temps closely.

Seamless Integration with Your Marine Electronics Network

Designed for NMEA 2000 compatibility, the sensor plugs into your existing setup using a straightforward T-connector. No complex wiring—just secure the thru-hull mount, route the 10-foot cable, and watch data populate across Lowrance, Simrad, or B&G displays. Pre-set for water temperature, it shines in versatility: reconfigure it via compatible multifunction displays to track engine room heat, cabin comfort, live well stability, bait well chill, refrigeration units, heating systems, or ambient inside/outside conditions.

Built for Harsh Marine Conditions

Crafted with rugged black housing, it withstands constant submersion, UV exposure, and impacts common in saltwater or freshwater environments. The wide operating range from 4°F to 176°F (-20°C to 80°C) covers everything from icy northern lakes to tropical bays. Suited for hulls up to 1-1/4 inches thick, installation remains straightforward with the included locking nut for a watertight seal.

Simple Installation Tips for Optimal Performance

  1. Select a spot below the waterline, forward of any prop wash for clean readings.
  2. Drill precisely, apply marine sealant around the thru-hull, and tighten the locking nut firmly.
  3. Connect to your NMEA 2000 backbone via the T-connector—power cycles automatically.
  4. Calibrate on your display for pinpoint accuracy, adjusting for any hull-induced offsets.
  5. Regularly inspect the cable and mount during routine maintenance to ensure longevity.

Users report hassle-free setups in under an hour, transforming raw network data into actionable overlays on charts and sonar screens.

Real-World Applications Beyond Basic Boating

Fishermen layer temp data with structure scans to pinpoint thermoclines where species congregate. Commercial operators monitor bait wells to keep catches viable longer, reducing waste. Sailors track sea temp gradients for tactical routing, while cruisers use it for liveaboard comfort by overseeing cabin and engine spaces. Its 5-pin wired design ensures stable, drop-free connections even in rough seas.

Frequently Asked Questions

What displays are compatible with this thru-hull temperature sensor?

It works with Lowrance, Simrad, and B&G multifunction displays and gauges connected to an NMEA 2000 network.

Can the sensor measure temperatures other than water?

Yes, it's pre-configured for water temperature but can be reconfigured for engine room, cabin, live well, bait well, refrigeration, heating, inside, or outside temps using compatible displays.

What is the maximum hull thickness for installation?

It supports hulls up to 1-1/4 inches (31 mm) thick for secure, leak-free mounting.

How long is the cable included with the sensor?

The sensor comes with a 10-foot (3-meter) cable for flexible routing to your NMEA 2000 backbone.

Is professional installation required?

No, most users install it themselves with basic tools. Follow thru-hull best practices: drill accurately, seal properly, and connect via the T-connector.

What makes thru-hull mounting better for temperature readings?

Thru-hull placement delivers true subsurface water temperature, avoiding distortions from surface air, waves, or engine exhaust.

Does it require separate power or configuration?

It draws power from the NMEA 2000 network. Initial setup and reconfiguration happen directly on compatible multifunction displays.

Kit Contents for Quick Setup

Everything you need arrives ready to go: the thru-hull sensor with attached cable, locking nut for secure fitting, and NMEA 2000 T-connector for plug-and-play network access. No extra purchases required to start monitoring.

Add the Lowrance Thru-Hull Temperature Sensor to your NMEA 2000 network to monitor water temperature from the convenience of your multifunction display.
