External Fairings for Through-Hull Transducers
Fairings orient the sound beam straight down by mounting the transducer parallel to the water surface, and help to reduce turbulence. Transducers designed for use with a fairing must always have the fairing installed. Fairings should be cut to allow for hull deadrise and the removed top section should be installed inside the hull.
Always install the forward bolt to prevent fairing rotation.
