Bonding Plastic to aluminum

[Blue_Runner]

5200 might hold it, but I wouldn't trust it.

I don't know what would hold it. I would just drill holes in the transom and slop em up them really good with 5200 - water will never get in.

Also, filling the holes is an easy fix if you ever feel the need. Just do the old golf-tee-coated-in-expoxy-and-cut-the-top-part-off-flush trick. It will be an easy job than patching holes in aluminum or getting off whatever adhesive you might try to use.
