Let say the the stern of my boat had a narrow U that protruded from the bottom of the hull, if i filled the entire thing with epoxy and put a HB SI transducer in there would I get SI images?

As long as there isn't anything physically blocking
the beams from shooting out both sides, then it should
work.

“CAUTION: Before I discuss the subject below I want to make sure everyone that
reads this understands that the following isn't recommended or endorsed in any
way by Humminibird. I simply wanted to share this with the group for knowledge
sake.
I have created an ALBUM titled IN HULL SIDE IMAGING. In this album are two
images that I took using a Ranger Z 19 model year 2006 boat. I laid a regular
transom mount side imaging transducer in the bottom of the bilge area of the Z
19 and simply stuck it up under one of the bilge pipes ( no epoxy) . I had to
put approx one inch of water in the bilge area to make sure water was covering
the beams in the transducer. As you can see from the images it is possible for
side imaging to shoot thru the hull of a boat but keep the following in mind:
#1- In these images I have the sensitivity turned to max (20) and the images are
significantly darker than they would be if mounted on the transom.
#2- The results are going to vary dramatically from hull to hull. This is the
major issue in that if you try this on one hull it might work well but if you
mount it in another hull with either a different thickness or shape it might not
work at all.
#3- Even slight variations of the angle can cause significant differences in the
quality of the signal.”
This was posted by Mark Gibson (than the Hummingbird Brand Manager I think).
Compare these images to the images of the pool that you see in the simulator of your unit with the Sensitivity maxed out. I don't know if epoxy would be a better coupling medium than water or not. Maybe Rickard or one of the others who have built their own transducers can weigh in on this.
