i would go to your local gander or cabelas get the epoxy made for transducers. or call the mfg. Always a safe bet doing it that way.

any two part epoxy should work. There is nothing special about a transducer.

I just put one in and used 5-minute epoxy from walmart.

For the strongest bond youl want to use a long cure time. plus 30 min or longer will be waterproof.

i've used 5-minute epoxy on five different shoot-thru transducers with good results.

it held up great in the bilge area even though it gets wet. also, on one occasion my initial placement of the transducer wasn't in the right spot, something i didn't discover until days later out on the water. with some firm pressure i was able to pop the transducer free, reapply epoxy and stick it in a better place.

Umm transducer epoxy is specially made to not have tiny air bubbles in it. Use whatever you want but if you make a large investment like a nice fish finder just pay the $5 for the right epoxy...lol

is that kinda like how you "have" to pay extra for the "specially made" Optimax oil? lol.

even when you use the 2-part "specially made" epoxy that comes with new units, as soon as you start mixing it together you introduce air into the mix...tiny bubbles. whatever epoxy you use, you still have to properly settle the transducer into it to push the bubbles out.

i can only share my personal experience rigging my own boats with shoot-thru transducers the past 5 years. it's not hard, and i got crystal clear returns even at high speed using both standard store-bought epoxy and the epoxy provided with a new Humminbird.

I don't imagine the transducer is going to see a lot of force where I'm worried about it breaking loose.  If it does, I'll simply redo it...
