on my new boat, theres a Garmin 160 fish finder with a bronze transducer mounted as a through hull. This transducer measures depth, water temp and speed and has a cool plastic plug with a paddle wheel that goes through the transducer.

The previous owner told me that he turned it on by accident once when the boat was on the hard and the following spring it did not work and thinks that he fried the transducer.. I can't see why this would happen and wonder that it could be the fish finder that isn't working and with that logic, if I was to replace it with a nice chart plotter it should be able to pair with the transducer.

Has anyone heard of this problem?? I know it won't work out of the water because it needs water to cary the sonar, but how could this 'fry' it????
