my lowrance mark 5 pro also clicks, but seems to click more loudly when using 83MHZ and when i first fire it up.
i believe this is normal??
mine is installed using two purchased foam blocks stacked on top of each other with the transducer against the hull with a little bit of water underneath.
i read another post that someone else committed on the clicking noise.
