SILICONE to mount in-hull transducer?

Silicone??

That's what my instructions are saying, to use clear silicone! I had always heard they were epoxied in place, but the instructions say something about this way being better because it's removable. (The PO was very much in love with clear silicone, and used it ALL OVER my boat, and every time I find myself sanding it off I want to go find him and wring his bloody neck).

BTW, the instructions also go on to recommend glycol to fill the unit, which is something else I wouldn't have expected. Are they talking ordinary antifreeze?

As I am a sailboat neophyte, I appreciate any words of wisdom, thanks!

Re: SILICONE to mount in-hull transducer?

Is this to shoot through a solid f/g hull? In that case silicon will work perfectly with the following caveats; 1) make sure the transducer gets a clear reading through the hull at the desired mount location BEFORE mounting it permanently in place. KY jelly or vaseline makes a great temporary medium for this and 2) don't allow any air bubbles to form in the silicon during the installation process.

Dixie,

You might want to take a look at one of the projects web pages. It's at;
Guenevere's Projects, Depth sounder
and shows how we did a no hole depth gauge on our boat.

Re: SILICONE to mount in-hull transducer?

I've mounted several in hull transducers using silicone and it works great. I used a zip lock bag with mineral oil in it to locate a good location on the hull, then apply a large blob (technical term) of clear silicone. Hold the tip of the tube in the center of the location you've chosen and just squeeze it out around the tip, that results in the fewest bubbles forming. Just let the ducer settle down into it (angle it a bit at first to let air escape) and secure it with duct tape or something if it tends to move downhill on you.

Re: SILICONE to mount in-hull transducer?

I have installed one with silicone and many using epoxy which is recommended by most depth sounder manufacturers. Epoxy is the best in my opinion, bubbles aren't an issue. There is no real need to make it removable.

To find a good location I just place the transducer in a baggie of water and move it around until it works.

Here is a link to West Epoxy's instructions to install a transducer.

mitiempo,

I don't mean to be contrary, but the statement, "There is no real need to make it removable." sounds like some one who has never purchased a used boat, or owned a boat for more than a few years. EVERYTHING always needs to be replaced at some time or another!

I guess I am just a geezer.

Re: SILICONE to mount in-hull transducer?

It is removable, but not to re-use. A good whack with a hammer sideways will remove it. No reason to if it is working though.

There are few things on a boat that a good whack with a hammer won't set right.

Or the proper application of the correct amount of explosive!

Greg, that's essentially how my transducer (Airmar P79) mounts. It comes with a plastic cylinder "base", which is cut at an angle and flanged on one end. This end is placed on the hull, rotated until the top end is perfectly level, and siliconed down. After curing, it gets filled with propylene glycol and the 'ducer gets sealed inside.

I'm still surprised at the use of clear silicone, but if it worked for you, I'm sure it'll work for me! And I might very well have to move the 'ducer, since I was unable to test it with the boat in the water prior to mounting. I have it placed in the area recommended by Airmar, and where other owners of Catalina 22's have mounted theirs, so I hope my odds of success are at least pretty fair.

I'm not sure why Airmar recommends the propylene glycol, either, but I'll just roll with it. After some research, I've found Prestone "Lo-Tox" antifreeze uses propylene glycol in a concentration of 90-100%, according to their MSDS's. So, it's off to the auto parts store in the AM.
