I've been using a blob of vaseline for about a year now with no problems. I had to re-do it once because something got loose in the hull and knocked my transducer loose.
I wedged a section of pool noodle above the xducer to hold it in place. Not perfect, but I can't make up my mind where to mount it permanently. I have the slow-cure epoxy all ready to go and everything... :-)
