 Jon, No they can't shoot through steel only fibreglass. I had suggested making a tiny view port witha fibreglass disk in it to attach the transducer to from the inside of the hull. Not sure whether Hank is doing this or just fibreglassing the whole transducer and putting it in the water. I was told by a rep that the shoot - through-Hull transducers can shoot through up to 1/2". I did hear 1"from another source. Just important not to have any air gap or bubbles! Alan

  Not quite following you guys.  Are you say you are shooting through the steel hull?

 Hi guys. I have done just what Alan suggests. I bought a new transducer that shoots through the hull. I epoxied it to a heavy piece of fibreglass.  The transducers are potted, but when taking one apart I discovered there is little protection on the bottom side of the transducer. It varies from brand to brand I thinkHank
