Having difficulty getting my transducer to stay attached to the inside of the hull (through-the-hull transducer).

I used the epoxy that came from Hummingbird but it only lasted for three fishing trips. Seemed to stick well to the transducer, but not to the Hobie PA hull.

Suggestions?

Thanks in advance.

Get some Duct Seal Compound from Home Depot or Lowes, works great for installing the transducer and is easy to remove.
Just Google the install or search on YouTube.

A lot of guys use Marine Goop. I found that this works well initially, but develops tiny bubbles over the course of several months. I suspect that most of the easily removable adhesives will suffer this same fate. These bubbles cause acoustic impedance and result in noticably worsening sonar sensitivity with time. So I now use a "water sump" mount. Basically, use Goop to affix a collar of closed cell foam, cutout in the center to tightly accept your transducer, to the inside of the hull. Just before heading out, fill the cutout well with about 1 cm of water. Insert the transducer until it bottoms-out against the hull and squishes most of the water out. The idea is to have only water, no air bubbles, between the transducer and the hull (and the same between the hull and the fish, for that matter). This produces excellent sensitvity. I have modified mine with some plastic tubing that permits me to easily add water from the center hatch area using a plastic syringe, even though my transducer is located further forward. An easy mod with dramatically improved performance as compard to a permanent glue-in transducer mount.

Duct seal is in the electrical department at Lowes. It is in a white plastic wrap and comes in a bar that's about a pound. It's like a sticky putty / clay and works really well sticking to the polyethylene hull.

It is cheap too. One package is twice as much as you will need.

Another inexpensive option:

Your hull flexes, your epoxy does not. It's tough to do with epoxy.

If you attempt to use any sort of adhesive, remember not to scratch up the area you're going to adhere to as this weakens the bond. Just scour with Scotchbrite to create the water break free surface. Wipe with a solvent first, not after you scour the surface.

I used Marine Goop for years. Never had any problems with it.

Glad it works for you Islandspeed, but Goop caused problems with my FF. Next time you have to remove the transducer, look at the Goop. Goop dries clear, turns cloudy; the clouds are minute bubbles, each of which can cause acoustic distortion. I reinstalled with new Goop and had the same issue over the course of several months. I went the water-mount route and have had no similar problems for 2 seasons.

I also used Marine Goop for 5 years on my Native Wilderness, with no problems, and when I traded it in on my PA 12, it was really tough to get it off.
