Overview / What Is Furuno B175M/20 Transducer

The Furuno B175M/20 Transducer 85-135kHz 20 Deg Tilt 10-Pin is a medium frequency, tilted element thru-hull transducer built to deliver superior bottom tracking and fish target detection. Its 20° tilt is specifically designed for boats with a deadrise between 16°–24°, which means it ensures consistent and accurate echo return directly beneath your hull.

This model operates at a frequency range of 85–135kHz, offering better resolution than low-frequency units while still retaining solid depth capabilities. The 10-pin connector allows for quick plug-and-play integration with Furuno sounders and MFDs. The durable bronze housing ensures long-lasting corrosion resistance, making it ideal for saltwater and freshwater use alike.

Benefits of Using a Tilted Element Transducer

Tilted element transducers like the Furuno B175M/20 Transducer 85-135kHz 20 Deg Tilt 10-Pin offer a range of advantages over standard transducers. The 20° internal tilt means the transducer face sits flush to the hull and shoots the beam directly downward, minimizing signal distortion and increasing accuracy. There’s no need for a fairing block, which means easier installation and reduced drag.

This makes it an excellent option for fast center consoles and sportfishing boats that require reliable bottom detection at speed. The ability to maintain signal clarity at higher speeds makes the B175M/20 one of the best transducer options for offshore anglers and commercial boaters alike.

How to Install Furuno B175M/20 Transducer

Installing the Furuno B175M/20 Transducer 85-135kHz 20 Deg Tilt 10-Pin is a straightforward process, especially when replacing an existing thru-hull model. Always consult with a certified marine installer if you’re unfamiliar with hull penetrations.

1. Identify the Deadrise: Ensure your hull’s deadrise is between 16°–24° to match the 20° tilt model.
2. Drill Hole: Use the provided template or the included gasket as a guide. Use marine sealant before securing the bronze housing.
3. Wire Routing: Route the 10-pin cable to your Furuno sounder or MFD. Secure with cable ties and avoid areas with high heat or moving parts.
4. System Integration: Power up your Furuno system, navigate to the transducer setup, and configure frequency and range preferences.

Important: Always use marine-grade sealant around the hull opening to prevent leaks and corrosion.

Maintenance Tips

To ensure long-term performance from your Furuno B175M/20 Transducer 85-135kHz 20 Deg Tilt 10-Pin, follow these maintenance tips:

• Routine Cleaning: Check for marine growth every few months and clean using a soft cloth and mild detergent.
• Inspect Cables: Look for wear or corrosion on the 10-pin connector. Replace or repair as needed.
• Winterization: If storing the boat for winter, inspect the transducer before and after storage to ensure it remains watertight.

Regular maintenance improves both the performance and lifespan of your transducer, giving you reliable sonar data when it matters most.

Furuno B175M/20 Transducer Troubleshooting Guide

Occasionally, users might experience issues with the Furuno B175M/20 Transducer 85-135kHz 20 Deg Tilt 10-Pin. Here are some common problems and solutions:

• No Sonar Return: Ensure the cable is connected securely and not damaged. Reset your MFD and check software compatibility.
• Distorted Readings: This may be due to turbulence from the hull. Ensure the transducer is mounted clear of strakes or steps.
• Loss of Bottom: Reduce speed to verify performance. At high speeds, incorrect mounting angle can cause issues.

Detailed FAQ Section

Is the Furuno B175M/20 Transducer compatible with all Furuno units?

While the Furuno B175M/20 Transducer 85-135kHz 20 Deg Tilt 10-Pin is widely compatible, it’s essential to check for specific model support. Most modern Furuno sounders and MFDs, such as the NavNet TZtouch and FCV series, are fully compatible with the 10-pin format. However, older units may require adapters or software updates. Always consult your product manual or Furuno tech support for compatibility confirmation.

How deep can the Furuno B175M/20 operate?

Thanks to its 1kW power output and medium frequency range (85–135kHz), the transducer can detect targets to depths of up to 1500 feet or more, depending on water conditions and bottom composition. Its performance is excellent in both deep offshore settings and shallower coastal regions, making it versatile for multiple applications.

Can I install this transducer on my own?

Installation is possible for experienced DIY boaters familiar with thru-hull installations. However, due to the importance of hull penetration, professional installation is strongly recommended to ensure safety, water-tightness, and optimal transducer angle. A poor install can lead to signal loss or even hull damage over time.

What makes the 20° tilt important?

The 20° tilt allows the transducer’s sonar beam to shoot straight down, even when installed on angled hulls with 16–24° deadrise. This ensures accurate and undistorted readings, maximizing your ability to identify structure, bottom contour, and fish directly beneath the boat. Without this tilt, sonar beams would be skewed, reducing detection quality.

How does it compare to low and high-frequency models?

Medium frequency models like the Furuno B175M/20 offer an excellent compromise between the depth penetration of low-frequency (typically 50kHz) and the detail of high-frequency (200kHz). You’ll get better clarity in moderate depths and good bottom tracking in deeper waters, making it suitable for both inshore and offshore fishing.

Conclusion

Whether you’re a professional angler, charter captain, or marine enthusiast, the Furuno B175M/20 Transducer 85-135kHz 20 Deg Tilt 10-Pin is a highly reliable, durable, and high-performing sonar solution. It delivers accuracy, depth, and clarity, making it a valuable investment for any serious boating setup. Thanks to its medium frequency design, flush mount, and compatibility with Furuno systems, this transducer stands out as one of the best on the market.
