OK, me bad. Now I’ve got a working 50/200 transducer that took me a very long time to find,
that has been cracked off at the bolt hole, a common problem.
Anyone ever had any success with repair methods on this?? JB Weld???
Yes, it is a faint hope, but I gotta try rather than go to my 200 backup…
They look like they’re made out of plastic, I’m wondering if epoxy wouldn’t work better?

x2. I would use some good 30 minute epoxy applied liberally. It may not look the best but that stuff is strong.
I have used epoxy with good success. I wrapped the transducer with braded line and then epoxied over it. I too broke mine near the mounting hole. Just rough up the area where it broke with sand paper. It worked great and still is on the boat 6 years later.
I broke mine (Lowrance 520) off at the mounting bracket where it necks down to narrow. It is some kind of Bakelite style plastic. Nothing I tried worked, several epoxies, super glue, JB weld etc… I called both Lowrance and Cabela’s and was told by both that it is a common problem but they know of nothing that works. I finally took some silicone tub sealer and built up about 4 layers thick allowing dry time between each coat. I wound up with a big glob of pliable sealer covering all but the bottom, but it held. I like the twine wrap with epoxy idea mentioned above. I would try that if there is a next time.
buy a new one for like 50-60 bucks, or whatever they cost.

I would agree normally, but this is going to be a recurring problem here, so I may as well get on with fixing this one.
I’m wondering about a metal reinforcing strap going around the bolt hole. Maybe drill a few holes thru the strap for the JB to ooze thru. Anyone tried that??

The “braid and epoxy” would probably be stronger if it will work with your break. Think how strong the wraps on your rods must be, and those are just nylon thread instead of spectra.
If you post a pic of the break that may help generate additional ideas.
Good luck.

my break cracked the bolt hole in half, hence the thought about the metal reinforcing… A “U” shaped support is needed. It might help to braid down the two legs of the “U”, and I’ll probably do that, but it’s at the bolt hole that support is needed and that area can not be braided…
buy a new one, and be more careful with it… 
i’ve never broke a transducer, and i’ve hit a lot of things you’re not supposed to.
Would if I could, but with 40 dogs and 3 non-fishing employees on site, i’m lucky if anything still works!!
Did a little searching and it seems a 106-23 is pretty hard to find and expensive if they show up. Anybody got one laying around they want to sell??
You got a pm
Well, Dougie came thru and I’ll be putting a new transducer on board. Thank you, Dougie.
BUT, I always like to carry a second ‘ducer on fishing trips, so I figured to repair this one and use it as a back up.
Thought some might like to see what I’ve done as per the above posts.
The “U” Reinforcement
This is a ?1″? metal pipe wall clip that has been worked over.
The ‘Scored’ Parts
The PreJB Fit
After First JB and Threading
I used PowerPro 15#, about 5+ yards.
I’m thinking a second layer of JB tomorrow after everything is tightened up.
Then will flat sand and re-cut notches for the washers.
It will be in the mail tomorrow.
I used a different type of epoxy. your idea looks good. I guess I forgot to mention that I did drill two small holes on the transducer and screwed in two very small screws and then wrapped it with braid. I actually used fireline 10 lb test and wrapped it. Mine also broke in a similar fashion as your’s did. You know it may not look pretty when your done, but it sure is fun to try and figure out how to fix things up. I like your idea. 
I tried to keep my holes pretty surface as i didn’t know anything about their wiring paths (I WILL after i destroy one of these and with my habits, that shouldn’t be too long…)
What I do think is critical is the use of a slow drying epoxy. This one (JB Weld) proofs at 3960#, but most of the fast expoxies are in the 2400# range.
If this works out well, I may do it pre-emptively on all my transducers.
I may also take out the toothed washers and put in big SS fender washers, so you kinda have the ‘rubber hub’ effect that props have. Would have saved this ‘ducer in this situation. clipping a log at WOT, well, you’ve got bigger problems then…
