Default Alumaducer (shoot thru transducer for aluminum boats)

I keep losing bottom signal with my transom mounted transducer on my 16ft. aluminum flat boat. I suspect turbulence from the trim tabs. I have thus far been unsuccessful with software, height, and angle adjustments (don't know how I'd "test mount" it further from the trim tabs).
From what I understand, but please chime in if you disagree...I cannot use a "Shoot Thru" transducer in an aluminum (.100 gauge) boat.
I have found this product http://www.vexilar.com/products/alumaducer.html which is a shoot through transducer made for aluminum boats. Does anyone have any experience with this product or a similiar one? Also, do you think I could mount it with silicon instead of the epoxy?
PS. I don't need fish arches and alot of detail displayed etc., I mainly just want to know the depth of areas that I am running. Typically 1 to 20 feet.
thanks

Hooked,
Try removing the Tab nearest your transducer. Tape it to the hull or whatever. No need to disconnect your hyd lines.Then run the boat.See if there is any difference.
To test different positions for the transducer, use a piece of 5ply, screwed into the original td holes & mount the td onto the ply. Gives you heaps of options without drilling more holes in your hull or mounting bracket.
You do not mention what sounder you have but my Raymarine L760(Transom td) would give a clear bottom picture at 20+ knots in 100 ft.

I have an aluminum skiff and have had no problems shooting through the hull with a conventional transducer. Took it off the transom and mounted it to the floor with epoxy. Works just like it did before (maybe better).

Why not just take your existing transducer and temporarily install it as a shoot through and see what the results are? You might be pleasantly surprised. Just make a dam of clay in the bottom of your boat just big enough to surround the transducer. Put some mineral oil in there and then hold the transducer in place while you see how it performs.

1) Cannot remove the trim tabs, welded on.
2) The current transducer is attached to a bracket which is welded on and protrudes about 1/2"-1" from the transom. That may be difficult to attach a temporary bracket to but I can get creative. (What is 5ply?)
3) The unit is a Garmin 188C
4) How thick is your aluminum hull that you are successfully shooting through?
5) What is the mineral oil for and how do I hold the transducer in place temporarily, I've heard of putting it in a glob of Vasealine.

Thanks and sorry if some of these questions seem remedial.

Hooked,
5 ply is plywood. "5" denoting number of layers. About 1/2 inch thick.

Hooked, the key to a thru hull is NO AIR between the puck and the water. Epoxy, water bath, vasoline, whatever...make sure ther is no air or it will not work. There is no harm it trying to shoot-thru. Right?
