Used plumbers putty so far to put the transducer in the forward lazarette in the cabin but it gets loose over time. Epoxy any good? Thoughts....?

I use a slow set epoxy (1 hr+) and use a weight to press the transducer firmly to the hull while curing. Try to ensure there are no bubbles in the mix. Thats why slow set works well.

Some folk use a toilet bowl wax ring instead of plumbers putty. It does not dry out like putty. Epoxy will be a permanent solution. Clean up all the putty both on the transducer and the hull before you glue it down.

3M 5200 works?
Even if it does, it seems a bit permanent for a device that might break or need to be updated in several years. I've used silicone caulk, which worked fine and for me was a reasonable compromise between durability and removability.

I have used thicken West Systems Epoxy to secure the transducer on several boats I have owned. On my Capri 22, I placed the transducer in the forward storage area as far back as I could – looking in front of the keel yet still in quiet flow.

The transducer is designed to be transom mounted, but that doesn't work for sailboats.

I had to remove an older functioning transducer last month to mount a newer design to go with my new chart plotter. Since I use a liberal amount of thickened epoxy, I used a vibrating multi-tool to begin a fracture point of the epoxy. Couple of taps later with a chisel, the transducer came out with no damage.
