I'd heard that Silly Putty works. Nice to hear from an actual user that it does so well.

Try Silly Putty or one of it's generic counterparts. I have my transducer "permanently" installed with it. Been in there for 2 seasons and has never failed. I got it at Wal-Mart (generic) for $.99! Just make sure you install it over solid f-glass and you're all set. Lewis Baumstark West Wight Potter 15 Bristol, TN
