Transducer question...

[Hooked Up]

I have been told by several people that I can use a thru hull transducer in my boat without cutting a hole in the hull. Simply by adhereing it inside the hull in the vee by carefully resting it in silicon and being careful to get all of the bubbles out.

Has anyone here tried or know about this? Any and all feedback is appreciated.

Yes sir, I've shot through the hull on several fiberglass boats. I used fiberglass resin as my bedding material being very careful not to have any bubbles. I've never heard of using silicone, but that doesn't mean it can't be done.

Shoot-thru-hull transducers are epoxied directly to the inside of fiberglass boat hulls. The sound is transmitted and received through the hull of the boat - but at the cost of some loss of sonar performance. (You won't be able to "see" as deep with a shoot-thru-hull transducer as one that's mounted on the transom.) The hull has to be made of solid fiberglass. Don't attempt to shoot through aluminum, wood, or steel hulls. Sound can't pass through air, so if there's any wood, metal, or foam reinforcement, it must be removed from the inside of the hull before installing the transducer. Another disadvantage of the shoot-thru-hull transducer is it can't be adjusted for the best fish arches. Although there are disadvantages to a shoot-thru-hull transducer, the advantages are considerable. One, it can't be knocked off by a stump or rock since it's protected inside the hull. Two, since there is nothing protruding into the water flow, it generally works quite well at high speed if it is mounted where a clean laminar flow of water passes over the hull. Three, it can't be fouled by marine growth.

OK one last question....

If I put a thru-hull transducer in actually through the hull....what danger lurks when trailering my boat.

Thanks
