I have recently purchased a Garmin 545s gps. Existing on my boat are two through hull fittings, one for depth and one for speed. Both are Datamarine products. my question is, will a Garmin transducer adapt to the older existing through hull. I want to unscrew the old Datatmarine and install a new Garmin transducer. I called Garmain and they did not have an answer for me. Has anyone had any experence with this situation? I do not want to use a "shoot through hull transducer". So before I pull my boat out of the water and redrill a new hole I thought I might get some information.

I don't know the answer to your question, but why are you certain you don't want to do a shoot thru hull set-up?

Kms, I'm doing the same thing--Garmin 545s, old Datamarine transducers, etc. But I'm ignoring my old thru-hull transducer and going with the shoot thru the hull type, as T34C has suggested. Won't have to worry about the transducer getting fouled this way.

And next time the boat is on the hard for a bit, I'll glass over that thru-hull--one less hole to worry about.

I haven't completed the process yet, so no first-hand knowledge here--but if you search on in-hull transducers or shoot thru you'll find info on how to set them up.

Although it's a different brand, I just installed an inexpensive uniden thru-hull, in an existing location, by cutting out the 30 year old plastic (plug type) thru-hull. Very easy to cut out old one, clean up areas with sander, dry fit, and finally install the new one. I doubt if the old thru hull will accept the new one, from a different vendor, but cutting it out, and installing a new one was easy.

I tried a shoot through one last year, but got intermittent errors, despite being a solid glass hull. Since the old hole was already there, I decided to use it.
