Check this :-http://www.boatingdirect.net/browseproducts/
This Transducer is compatible with many of the Raymarine sounders.
I have not used an In-Hull transducer on a steel boat - but have successfully installed a standard through-hull without cutting a hole in a fibre glass boat,
:- 6 inch length of PVC pipe glued with epoxy to the hull, fill with enough glycerine to cover at least 1" of the transducer head. - drill hole through cap to fit over pipe - pass wire through the hole - place cap back on pipe.
Good luck !
