I just purchased a 1984 13-foot Boston Whaler boat. I would like some information on mounting a depth gauge transducer. Will a transom mount work well at speed? Can a through hull be installed with the foam core construction? Will the transducer shoot through the foam core from inside the hull? ex: through a glob of silicone Any ideas to share?

A transom mount will work on a whaler as well as it will work on any boat when properly installed - which is to say it should work just fine. Just don't put it directly in like with one of the strakes on the bottom.

Whatever you do, don't go cutting holes in the bottom of a 13 to install a transducer.

I doubt that installing a transducer on the inside of the hull would work well because all that foam is going to be an excellent insulator of sound.

You can also read the original instructions provided by the Boston Whaler company regarding installation of a transducer on your boat. I have reproduced the original owner's manual for your convenience. Please see:
