Thru Hull Transducer on Aluminum-Do they work? 5 Months ago
Karma: 0  
Any comments about depth sounders using a thru hull transducer on an aluminum hull? I've seen one advertised that is supposed to work on an aluminum hull. A number of years ago I installed a thru hull transducer on a fiberglass hull and it worked perfectly, however, I'm skeptical about a transducer working thru aluminum.
