Mac,
I have seen this happen with Goop many times. You get the goop applied perfectly clear when mounting the transducer, only to find it filled with thousands of very small bubbles a day later. It always appeared to happen when the air temperature got hot during the 24+ hours it takes Goop to initially cure to a solid. Finally, one day I actually read the application intsructions on the Goop packaging instead of the tube (Doh!!), and it says "best when used between 70F and 85F".
I live in Rancho Cucamonga, CA and it often gets over 80 during the day many days of the year. I'm guessing Goop sort of 'boils' if it gets too hot during curing and that's probably how all the tiny bubbles(Don Ho be damned) mysteriuosly turn up. I have gotten 'clean' applications in the winter and the FF works perfectly, but when the thousands of minute bubbles are scattered throughout the Goop, my sonar still functions fine but is definetly less sensititive.
A while back someone had mentioned using aquarium silicone with good results. So I got a tube of DAP Silicon Aquarium Sealant at Home Depot and it worked perfectly without forming any bubbles although it doesn't seem like it will last as long as Goop since it's somewhat softer; we'll see. I figure it will hold until the cooler months when I can do a clean install with Goop.
Just my observations; your mileage may vary.
Keith
