How to Install Airmar SS175C Si-Tex 8-Pin on Your Boat
Installing the Airmar SS175C Si-Tex 8-Pin requires precision and adherence to marine best practices. The unit should be mounted where there’s minimal turbulence—typically forward of props and strakes.
- Drill a clean, properly sized hole through the hull where the transducer will be mounted.
- Apply marine-grade sealant around the housing before seating the transducer.
- Secure the nut and washer from the inside hull and torque to manufacturer specifications.
- Route the 8-pin cable through a waterproof cable gland and connect it to your Si-Tex sounder.
- Run a sonar check to verify installation, frequency response, and signal stability.
Always review the Si-Tex and Airmar installation guides to avoid common mistakes. Improper installation can lead to cavitation, poor readings, or hull leaks.
How Airmar SS175C Improves Si-Tex Sonar Systems
The high-wide CHIRP technology utilized by the Airmar SS175C Si-Tex 8-Pin offers a major upgrade over conventional single-frequency transducers. By sweeping frequencies across a broad range, it produces sharper sonar images, reduces noise, and improves target separation at all depths.
When paired with Si-Tex processors like the CVS-128 or CVS-1410, this transducer enables unmatched clarity and resolution. It’s especially effective for locating tightly clustered fish, navigating structure-rich seabeds, or distinguishing fish near the bottom where traditional sonar fails.
Maintenance Tips
To maximize the lifespan and performance of your Airmar SS175C Si-Tex 8-Pin, incorporate the following maintenance practices:
- Monthly Inspection: Check for marine growth, barnacles, or algae on the transducer face.
- Soft Cleaning: Use a non-abrasive cloth with mild soap. Avoid metal scrapers or brushes.
- Annual Resealing: Inspect hull sealant annually. Reseal if signs of degradation appear.
- Firmware Updates: Keep your Si-Tex system updated to optimize CHIRP compatibility and performance.
Pro tip: Use anti-fouling paint approved for transducers to reduce bio-growth in saltwater environments.
Expert Advice and Pro Recommendations
Marine experts widely recommend the Airmar SS175C Si-Tex 8-Pin for offshore anglers, deep-sea researchers, and commercial vessel operators. Its 25° beamwidth delivers excellent coverage, making it easier to identify bottom contours and schooling fish without multiple passes.

Understanding CHIRP Sonar vs Traditional Sonar
CHIRP sonar sends a continuous range of frequencies instead of a fixed frequency, offering better resolution, noise filtering, and target separation. With the Airmar SS175C, you’ll clearly see fish arches, bait clouds, and bottom structure in any water column.
Traditional sonar, on the other hand, operates at a single frequency, which limits its depth accuracy and makes it harder to distinguish fish from clutter. CHIRP is superior for almost all marine use-cases—from sport fishing to underwater surveying.
Performance & Durability in Harsh Marine Environments
The stainless-steel housing of the Airmar SS175C Si-Tex 8-Pin offers excellent corrosion resistance, even in saltwater environments. This makes it one of the best transducers for long-term reliability, especially for offshore boats or commercial vessels exposed to the elements.
Its solid-state tilt and sealed components withstand impact, water pressure, and vibration without signal degradation. Combine this with Si-Tex’s rugged sonar systems, and you get a bulletproof sonar solution.
Detailed FAQ Section
How do I know if my Si-Tex unit is compatible with the Airmar SS175C 8-Pin?
To verify compatibility, refer to your Si-Tex sonar model’s user manual. Most models that support high-frequency CHIRP transducers will clearly list compatibility. Units like the CVS-126, CVS-128, and CVS-1410 series are generally compatible with the Airmar SS175C 8-Pin interface. If unsure, you can contact Si-Tex support or your equipment supplier with your display model to confirm compatibility.
What is the typical cost to install the Airmar SS175C-12-HW 8-Pin?
Installation costs depend on boat size, access to bilge areas, and technician rates. DIY installs may cost $0 beyond tools and sealant. However, professional marine techs often charge $300–$700 for a full installation, including sealant, hull drilling, and sonar verification. Installation quality is critical to signal performance, so investing in professional help may save time and issues in the long run.
How does the Airmar SS175C compare to dual-frequency 50/200kHz units?
Dual-frequency 50/200 kHz transducers operate on fixed bands and provide limited clarity, especially in deeper or cluttered environments. The Airmar SS175C’s CHIRP system sweeps 150–250 kHz, resulting in better resolution, target separation, and minimal interference. You’ll notice clearer arches, smoother bottom returns, and the ability to distinguish individual fish in schools. It’s a superior system for anyone serious about sonar performance.
Can the Airmar SS175C be removed and reused on another vessel?
While technically possible, removing a thru-hull transducer like the Airmar SS175C requires patching the hull and drilling a new hole on the second vessel. This process may damage the transducer or reduce watertight integrity if not done properly. If you’re planning to upgrade boats soon, consider this when investing in a permanent thru-hull solution. Otherwise, consult a marine technician for assessment and reinstallation procedures.
What kind of warranty comes with this transducer?
Airmar typically offers a one-year limited manufacturer warranty for the SS175C. This covers defects in materials and workmanship but does not cover damage due to improper installation or water intrusion from sealant failure. Always install using Airmar’s official procedures or with a certified installer to protect your warranty status. If purchased through allboatsupplies.com, warranty support and return policy are handled promptly and efficiently.
Conclusion
The Airmar SS175C Si-Tex 8-Pin is a high-end sonar transducer that delivers outstanding performance for boaters who demand clarity, range, and reliability. Whether you fish recreationally or work commercially offshore, this transducer ensures your Si-Tex system reaches its full potential. With solid construction, wide CHIRP coverage, and powerful returns, it’s among the best thru-hull CHIRP options available today.
