The best way to install a transducer on a kayak

I think the well system made of Duct Seal is the best for installing a transducer on a kayak hull. (thru-hull). I is easy to make, easy to undo or redo. No tools are required at all. No sanding no heavy cleaning required at all. It is the cheapest and the fastest. There is no waiting time. You make it and go fish. Though, I found that gluing the transducer on the hull, regardless of glue types (including Duct Seal), is not quite dependable. Because there is an inherent problem that is air pockets or air bubbles form between the hull and the transducer. Build a well for the transducer and fill the well with water is the best way to achieve consistent and accurate readings for a long period of time. On the video, I explained and demonstrated why a transducer well made of Duct Seal is the best way for installing a transducer on a kayak hull. Joe

So, I'm going to leave a bit more space, (front and rear) so the antifreeze doesn't get in between the transducer and seal. I think this is key. Water I don't think it's a good idea for the well, as it will evaporate in short order, and if you live in a cold climate, then you have to drain and redo this every year. Antifreeze doesn't have this problem.
I like the fact it's not permanent, just in case you happen to find a place on the hull that has voids. This can happen with fiberglass hulls.
For testing purposes, you can put your transducer in a Ziploc bag with water and throw a small sand filled Ziploc on top of that and drive around, make some turns, change speed, etc. If everything looks good, go to the duct seal.
The well is key, (and space) so that the antifreeze doesn't get between the seal and the transducer. It works, but follow these steps!

Helped me out a lot!!!!
I'm enthusiastic about the use of duct seal to build a well. I built a well using a PVC pipe coupling, which I glued to the hull.. The Hawkeye 3355 transducer is round, so it fit in the pipe-dam nicely, and the fish finder worked. I, too, have 3 kayaks, so it would be easy to move the transducer from one to the other using a dam, whether made of Duct Seal or PVC pipe. It only has to hold water, and you say only 1/8" of water. The receiver of my Hawkeye quit working, so I've got to buy another fish finder. I think I'll try the Humminbird 4088301 PiranhaMAX 153 Dual Beam Fishfinder. It's cheap and has dual beam. (I wonder if that will work in a dam.) I'd like to have the receiver mounted rather than portable like the Hawkeye. Too much clutter having the wire leading to my PFD.
So, the duct seal sticks to the hull well enough to form a dam and stays flexible so it can be molded over the transducer to help retain it. Perfect!
