Thanks for the reply. I did a little research on the Hummingbird website and they recommend to NOT use silicon as it gives inconsisitent readings. I guess I proved them right. I asked a local boat supply place about Goop and they didn't carry it but said they had silicon. I assumed that is what the Goop was. That's what I get for assuming. I am going to remove the transducer tommorrow along with all the silicon and try again. What type of material exactly is Goop and is it removeable? Hummingbird recomends a slow set 2 part epoxy. I didn't really want to use that as I figured it would be much more permanent (in case I screwed up or it wouldn't work right).
