Just a dumb question

Goop does not develop air bubbles over time, this only occurs during the curing phase, once it is cured it is stable. The air bubbles come from chemical outgassing and usually indicate too much Goop was used, or you had contamination on the mating surfaces. Clean everything with alcohol. You want a very thin layer of goop if you use that method, sound doesn't travel through a thick layer of goop very well even if no bubbles, it will actually become an attenuator.

I had two gooped & they worked fine. However I decided to upgrade when my old ducer went bad so I decided to cut the hole. After the cut I just kept thinking I just %$#^%$ed up my yak.

Here's the thread on another site, rather than reposting everything

Difference is night & day. I can watch my bait all the way down in 100 ft of water. No leaks yet, but I still check frequently

This Goop your talking about: What name brand is best and where can I purchase it?
I'm assuming marine goop?

Marine Goop - part of the Goop line of products.



OEX sells it, as does http://www.kayakfishingsupplies.com/...ne-GOOP/Detail

I've given up on gluing down my transducers , seems I can't do it without getting not so great reading and it always pops off every month or so, then I have a transducer with dried goop all over it, I have to deal with.

I bought a humminbird fish-finder and their scupper transducer. Simple to install, great reading, no glue or hole drilled in the kayak.

This may be the root of my problems with goop. I always figured the more the better

Exactly. Goop will not "develop" bubbles If there are bubbles, I would say that the install was the issue, not the goop. Also you gotta prep the surface well. This means scuffing the surface good with a heavy grit sandpaper, and making sure there is no plastic dust left. I had to sell my first hobie with the 'ducer still installed, because I literally could not remove it. I tried prying it with screwdrivers, scrapers, even tried cutting it out with a razor, but it was stuck so bad that it wasn't going anywhere. Goop is some sticky stuff, and you do not need alot of it.

Second that......I still have my old transducer stuck to the inside of my yak. I was afraid of doing damage trying to get that thing un stuck. No wires to it. It's just a permanent fixture now.
