I'm selling an unused new-old-stock Airmar B45 bronze thru-hull transducer with attached cable. Label shows Airmar part number 31-272-2-01 and an 8-pin connector. Bronze housing with threaded stem and fairing-style base as pictured. This is NOS: it has not been installed, but it’s been stored for a while, so the bag/label shows handling and storage wear. Please verify compatibility with your sounder/fishfinder and connector type before buying. You’ll receive exactly what’s shown in the photos.
