Transducer help for Humminbird 597 ci hd

I have a Humminbird 597 ci hd on the transom and have knocked off the transducer three times. I took the broken transducer and sat it inside the hull and it seemed to be reading fine. Not quite as sensitive but pretty good. Can you put the transducer inside an aluminum hull, I have heard different things about this. Does it have to be submerged in water inside the hull? Does the 200khz or the 83khz work better if it's in the hull? If not are there any recommendations on how to protect my transducer bc this is getting expensive. Also the break away feature on the bracket does not work very well it breaks away on a strong wave. Any advice is much appreciated.

You must be fishing some strong timber to get it knocked off/broke 3 times. Can you explain how a strong wave can break the mount?

I've heard that a you won't get a good or even decent reading when trying to shoot thru a tin hull but you say you are getting decent readings so why not try a temporary mounting inside the hull and see how it does. You can use plumbers putty or silicone/goop to mount the xducer to the tin hull very similar to the way kayakers do it. check out youtube or some of the kayak forums and see how different people have mounted their xducers on yaks. Using silicone/goop you need to make sure there are NO air bubbles in the goop as air bubbles will degrade the results. Most of these ways are temporary so you can remove it and try something else. Post up some results.

If you are going to try mounting the transducer inside-the-hull of an aluminum boat than I would do so with a piece of PVC pipe silicones to the hull and filled with water.

Now that's interesting ...

I've never seen that option before...

Jimp I have knocked it off on a tree once at Lake Fork, once at my home lake, and once at the Lake of the Ozarks on an interior door that was floating in the water. I guess I'm having bad luck. The transducer has a break away feature that when it is hit it is suppose to break away so it won't snap in half. The prob is the break away feature is junk and not very strong so that even going thru rough water it will break away. Then the transducer is shifted upward and doesn't read correctly. I screw the transducer in place but when I hit something the bracket or the transducer breaks. I think I will try these suggestions and see how it does inside the hull. On the 200khz level and the sensitivity turned all the way up it seems to read pretty good. Inside the hull the 83khz level is not very good but I rarely use that beam selection anyway. Thanks very much for the advice!!!

Guys at work are running a brass? xducer for a pro grade sounder in the little boat ( xpress 1754? W/40hp) for sounding small harbors and sloughs. PVC tube, place xducer, fill w/oil. This is for Corp-grade dredge surveys.
