Thanks for the help guys. I looked for Goop tonight and only found Plumbers Goop. It said it shouldn't be used on polyethylene??? I reattached the transducer with epoxy tonight and am not feeling great about it. I am afraid it may have a lot of real tiny bubbles in it. I will have to wait until the next time I can get on the water to check it out. Does anyone know how hard it is to remove epoxy if it still doesn't give satisfactory results??
