Transducers and Aluminum Boats

[Dannie Zimmerman]

I have a 17' Fisher bass boat with the transducer mounted on the transom just as it should be. Trolling around stumps,I managed to break the transducer mount 3 times in the last 2 years. During the 4th break, I managed to lose the transducer and mount. ($60.00). I asked the manager at the Fisher dealer if I could mount the new transducer on the inside of the boat. He said no. You can only do that with fiber glass boats. I didn,t give up yet. I talked to a friend of mine who has had several boats, and he said you could, but it had to be covered with water to work. I removed the acess panel at the back of the boat. Down inside is a well where the bilge pump and 2 live well pumps are located. I went to the lake, poured in about 1/2 gal of water into the well, and laid the transducer in there. It worked perfect. Later I used some marine epoxy and mounted the transducer, ran the wire and that was it. It works better now than it ever did! Don't let some one convince you that transducers
cannot transmit through aluminum. Dannie
