Depth Transducer Detached

I had the same thing happen to my 4460 last spring and the only step I couldn't completely do by directly was sand and clean the hull since the mounting point was just forward of the starboard engine and there was no way I could position myself to reach that are by hand. I ended up using sandpaper taped tight with a rag under it on the end of a cut off broom handle with the brushes cut off the broom. I also put the rag with some cleaning fluid after sanding on the same mechanism. I ended up going to the Marine store and asking what what the best epoxy to use and they pushed me to the quick set Locktite double syringe epoxy.

Because I couldn't reach the spot I ended up having to use the sending wire to lower the sending unit after putting the epoxy on the mounting side. Carefully placing it and then used the cut off broom handle again to hold it in place until it somewhat set.

Since you can reach your location, you'll have a better time getting it set. The most important thing from what I read when I did this is to make sure there is no bubbles or air left in the epoxy under the sending unit. That will affect readings, so do you best to mix it carefully to not allow for air bubbles. Pushing the unit down after putting the epoxy on it will also help with this.
