I called the Number -- Rep said no Body has this problem and had no answer of what can be used to Remove this Stuff that has leaked into the Lock on the TM base. I told her there has to be Something because where the Transducers are made it Gets on their Equipment --- her first statement was contact the Boat Manuf. or TM Manuf to see what to use. I said they dont use the Epoxy so there would not be an answer there.. After about 10 minutes she would have someone else call me from where they are Made. I got to get this Gunk out of the TM lock ...
