Garmin Mounting Hardware For GT/CV Series Thru Hull

The Garmin Mounting Hardware for GT/CV Series Thru Hull represents a critical component for anglers and boaters who demand reliable, permanent sonar installation on their vessels. This mounting system is engineered specifically for Garmin's GT and CV series transducers, which deliver high-frequency, high-resolution sounder data essential for modern fishing and navigation. Whether you're installing a new transducer or upgrading existing hardware, this OEM Garmin solution ensures your sounder remains securely mounted through years of saltwater and freshwater operation.

Designed as a thru-hull mounting assembly, this hardware facilitates a permanent, below-the-waterline installation that minimizes signal interference and maximizes sonar clarity—critical factors when distinguishing structure, baitfish, and bottom composition. The Garmin engineering behind this mount accounts for hull vibration, water pressure, and thermal cycling, using corrosion-resistant materials that withstand extended exposure to marine environments. Proper installation of OEM mounting hardware is vital; it prevents signal dropout, water intrusion, and the drift that can render your electronics unreliable when you need them most.

This mounting hardware is essential for GT21-TM, GT23-TM, CV23-TM, CV52-TM, and other compatible GT/CV series transducers found on center consoles, offshore vessels, and dedicated fishing platforms. Installation requires careful hull preparation and alignment; many boaters prefer professional installation to ensure watertight sealing and optimal transducer performance. Weighing just 0.62 lbs, the complete assembly integrates seamlessly with Garmin's ecosystem, allowing your chartplotter and sounder to operate without the performance compromises associated with non-OEM mounts.
