I did a similar repair to a transducer bracket a few years ago.

I used a two-part epoxy. I'd use a black one as it's UV resistant.

I also added a piece of nylon strap as a reinforcement.

Rough up with some 120-320 sandpaper, clean with alcohol or acetone if you have it, clean a piece of old nylon strap, mix the epoxy, if possible do both sides, puddle it on, work the strap into it, then work more into the top of the strap.

Although the cyanacrolate (sp) are good, you need a LOT of contact area to get good adhesion. It's usually hard to find the accelerator/primer also.

You could also use fiberglass as a reinforcement - main thing is to strengthen it.

Mine held for several years, was still on there when I replaced the finder.

I've used this technique for a lot of plastic repair - boat, car, truck and house items.
