For mine I cut out a perfect shape of foam that the transducer would fit inside of, glued it to the bottom of the hull with selleys all clear. Once dry this creates a well that holds water. Then push the transducer into this well, and whenever you go fishing fill this little well with water. This is called a wet mount, and is my favourite method.
The issue you might have previously had is air bubbles between the transducer and the hull. A good tip if glueing the transducer to the hull (this method worked for my last kayak for a couple of years) is to heat the selleys all clear in a bucket of hot water. This makes the silicone runny. Then cut the nozzle so it is a large opening, and start siliconing at one end of the foam well (using a foam well already glued down with this method helps the silicone pool up without running, and also gives some shock absorption if something loose in the hull slides into the transducer once set) in one smooth motion with the nozzle INSIDE the big bead of silicone run the bead to the other end of the well. If you go back and forth laying the silicone it will create air bubbles which will interfere with the sonar. Having the silicone warm and the nozzle inside the bead as you lay it prevents air bubbles. Mine did come unstuck after a couple of years, then I just trimmed the silicone off with a Stanley knife (didn’t have to be perfect) then glued it down again. This time I scuffed the surface up with 240 grit sandpaper, then when I got the PA I just pulled the transducer out of the hull.
