Brake lines and sticky pads are a well known issue on this web site...

They seem to last just long enough to get out of the dealer showroom...
In my state in Australia, motor registration would not even consider registering the trailer with the sticky pads and they had to all be replaced with zip ties and brackets. Sticky pads are deemed to be a non-permanent attachement for brakelines and therefore unsafe. For once they seem to be on the ball for a Government department
I'd definately be having that hull transducer installation looked at by the dealer - this doesn't look like it was factory installed at all. Looks more like a botched dealer installation to me and completely unacceptable. Almost seems like they drilled the pilot hole in the wrong place and then covered the screw up with a piece of tape..

Also clearly says on the label to "Remove this label after installation" so they didn't even do that, plus lots of scratches around the transducer where they have smoothed the edge with sandpaper - very disappointing and why I think it is dealer installed and not FW.
Can be easily fixed, so don't take any crap and press them to get it done right.
