Using acetone, clean the area where the transducer will be placed.
Break off a piece of Duct seal and roll it like modeling clay into a large piece of spaghetti.....maybe 1/4" to 3/8" in diameter and 6" long
Place the transducer directly flat on the hull and use the Duct seal to hold it to the hull by pressing it against the hull and transducer.
I built up the Duct seal around the transducer using several pieces....it will mold together just like clay and does a good job securing the transducer to the hull.
There will be no air gaps using this method.....Good luck!
Here we are again Dr.SteelheadCatcher
So I'm ready to setup my transducer for my Garmin Striker 4 unit and I'm going to use duct seal as well. I've watched a number of youtube videos and read other forums. Seems most people are using it to build a dam to hold some water so the sonar works. But this guy (video link below) just used duct seal, I just don't know if he used duct seal between the hull and the transducer (which I would imagine is better). Just simply placing the transducer flat to the hull is not a perfect seal, there's certainly an air gap there. What about using say an 1/8" or so bed first, maybe even warm the hull with a head gun (after cleaning the hull) and then the bed of duct seal might flow/adhere even better to the hull, then warm the bottom the the transducer as well when it's stuck to the duct seal? Then finally build up/shore up around the transducer with the remaining duct seal?
This is where I got the idea for duct seal, seems he's just using duct seal (even though there's water in the hull it's around on the outside, not sure it's in there for the transducer). I also got the idea for the mounting of my until on the side of the seat (my install shown in below images):
