They are not recommended for trailered boats as the transducer is not flush with the hull. Plastic Thru-Hull Transducers require that a hole be drilled in the hull and the shaping of a fairing block. Professional installation is recommended. Bronze Thru-Hull Transducers are an alternative to Plastic Thru-Hull Transducers. Plastic Thru-Hull Transducer shown is XTH-6-TB-90-P.
