Rode over a stick about the size of my arm yesterday and it ripped off the transom mounted transducer of my Hummingbird 100SX.:(
It broke the plastic lugs that mount the transducer to the mounting bracket.

So, money being a bit tight I started thinking about a repair. I was a bit pessimistic because I usually don't have much luck with plastic repairs where strength is required.

Heres what I did.

1st step was to clean up the broken ends and super glue things back together.

This was never going to be strong enough to tighten with the Allen key/bolt with out cracking again so I buffed it up with sandpaper and cut a wee patch out of a plastic ice cream container and glued it to the back, Then I cut he tip off a leather glove and glued it around the curve to cover the front fracture.

Once it was cured I then applied a liberal coat of Super glue to the outside of the leather and trimmed up the edges.

It seemed to work well and was strong enough to re-attach to the mounting bracket with reasonable force :D

Replacement Transducer =$140 :eek:

That must be an interesting-looking repair! How about a picture?

I think I would have given some fiberglass cloth and resin a try.

Re: Poor Mans Transducer Mounting Repair

There are several types of plastic. There are specific types of cement for bonding each of these. Use of the correct bonding agent is almost like welding. The two pieces bond together as though they were slightly melted. The repair will likely break along side the repair rather than at the repair. You just need to know what type of plastic you are dealing with.
