Transducer Removal

[Duke]

I am removing/replacing a plastic thru hull transducer that appears to have been caulked with 5200. Any suggestions on how to get the old one out short of a sledge hammer and drift?
Thanks,
Duke

If the one being removed is dead then destructive removal. Being plastic it is fairly easy to cut the head of it off outside the hull then just slice away at the caulk and or the unit until it gives up.
