no-thru hull transducer

I purchased a while back a Charlie Morgan sailboat that had a thru hull transducer but it was mounted inside a pvc pipe that was cut at an angle and sealed with what I think is 5200 glue. The previous owner told me he use mineral oil as the conductive medium between the hull and the transducer crystals. I do not have the details on how to do it but it makes sense - I sell ultrasound equipment for a living and a depth finder is just that - the key is to avoid any air and sand the inner hull to the fibreglass level here is what I also found on a couple of site: http://www.alcommarine.com/transducers.htm or http://www.lei-extras.com/tips/transducer/default.asp I recalled one boat site wheere the owner showed pictures of how he took a thru-hull transducer but mounted it without cuttng the hull - I just can't recall it but it worked for him. In my Cal39 I just replaced the old transducer - the hole was there already so no biggie ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

This is a good way I believe. Get an end cap sized for the pipe you use, or even a threaded joint adapter and a threaded end cap. Cut a hole in the end cap to fit the transducer. This will keep the mineral oil from sloshing around while offering a secure mount for the xducer. td From: Ca… [at] yahoogroups.com [mailto:Ca… [at] yahoogroups.com]On Behalf Of carlos Solanilla Sent: Friday, February 08, 2008 9:29 AM To: Ca… [at] yahoogroups.com Subject: [Cal_Boats] no-thru hull transducer I purchased a while back a Charlie Morgan sailboat that had a thru hull transducer but it was mounted inside a pvc pipe that was cut at an angle and sealed with what I think is 5200 glue.

Put me in the epoxy camp. I have a cheapo Horizon DF with the thru hull puck. Horizon's puck has an angle on the bottom so that you can spin it around until it sits level on a somewhat sloped surface. I actually epoxied it in place under the aft portion of my interior floor pan where it can't get bumped or have stuff fall on it. Another TIP: Mix the epoxy very slowly to avoid bubbles and let it sit a while before deployment. As for it's effectiveness, it reads perfectly to around 450' depth and then gets spotty over 500'. Like many sailors, my interest starts to wander after about 30'. Even contour navigation shouldn't require over 400'.

It was mounted to the lid of a box that was glassed to the hull and filled with mineral oil. The box and lid were 1/2 inch plywood and the top could be removed with four screws to inspect or change the transducer. Of course, newer transducers like the one I have now, also have other functions, such as a water temperature gauge, which would not be accurate in such a mount. The depth sounder worked fine.

Wilkie, Having spotty depth readings at over 500' depth? I can see this could be a problem if you boat has one of those new extreme estreme high aspect ratio keels that draws over 500'. You could easily run aground and sink her. What me worry? Shpritz jumped the sunken jetty while lost in the dark at the end of the Marina del Rey to San Diego Race, three years ago, wooooieeee! I draws only 2.5'. It did bang my centerboard a bit, which swung up into the keel when I struck the rocks. Ha Ha, I'll never do that again.
