transom area calk choice

[bandrus1]

I have an older 19.5 foot aluminum with outboard........ in the very back, where the transom meets the splash area there is some separation that causes leaking. Normal calk will fix this for some period of time but my guess due to trailering, the calk will eventually fail and if im trolling with the waves and it splashes over the back she will leak.

 

The transom seems fine it just flexing causing this. Should I try using 3M 5200 for a longer fix?

5200 is an adhesive and sealer.  4200 is just a sealer.
