Depth Sounder Transducer

[Zackman]

I have a Humminbird 600 depth sounder with a thru hull transducer. Looking at the transducer from the underside of the boat. while on the trailer, I noticed that a portion of the cover had cracked and half of it has come off.

Attached is a photograph. I contacted humminbird, but of course they no longer make this transducer. The original owner had installed this when the transducer installed by the boat builder stopped working.

The missing portion is on the trailing edge of the normal water flow. The transducer was installed by drilling a 2" diameter hole thru the hull.

It still works but I'm concerned about the integrity. What do you think are my options... Repair, replace, ignore ???

Before replacing it I would certainly try an epoxy patch. Tough to do from the bottom but worth a try.

Do you have any recommendations on the brand and type of epoxy that might work best?

I would think any fast curing 2 part epoxy should do the trick. It comes in a suringe type applicator. Try not to get to much on the face of the transducer. Cover the face with blue masking tape, then remove before epoxy dries.

If the tranducer sits in the water for a long time I would replace the transducer. You can never be to careful.

The "puck" of the transducer is a naturally occuring crystal in nature (usually) I doubt water would hurt it. The problem however is exposing the glued interface between the puck and the interconnecting wiring, including corrosion of the interconnect wiring and joint problems.

Epoxy patching the face is a great idea, just try to get all the bubbles out of the epoxy.

You can contact Hummingbird or Lowrance and they will tell you the preferred epoxy to use with those to minimize loss due to bubbles.
