Default 5200 no grip after 7 months ???

So i had a kplane cable leak (posted in my rebuild thread)
This i had to put here so hopefully i would get more answers ideas and advice.
Boat has 7 hours after rebuild, once the cable leak was found i figured better safe than sorry, so i checked the steering brackets bolts and they were packed full of 5200 and are dry but while taking them out, the brackets would have fallen on the ground if i let them.
They were installed in may 2018 and boat didnt go in the water till october.

As a precaution all the transom holes were taped off and i poured 635 epoxy in them and let them soak for 10 minutes, made a mess but it was piece of mind, now this.
Stuck/stumped, which way do i go ? How do i reinstall ? Why didnt the 5200 hold

i would be suspect of some kind of surface contamination on the stainless parts that were mounted, something petroleum based or ??? It doesn't take much just the slightest film because the surface is pretty fine and probably polished. What did you clean them with before mounting?

That looks like surface prep problem. I think the recommended cleaning prep after all loose dirt and debris is removed, is to wipe clean with mix of isopropyl alcohol? I know you can find on the 3M site. Hope this helps!

Wow fast thanks dave !
Machine/grinder finish on back from factory, and oily when received, nitrile gloves, acetone parts and transom.
5200 schlooped all over squeezed out of everywhere, torqued to 30 pounds. Maybe i just wasnt diligent enough
See every product stuck to the concrete just not the boat.
Holes have nice sleeve of 5200 all the way thru, guessing those will have to be cleaned out and totally redone as well.
Any special steps i should follow and what do you think 5200 or lifecaulk like was mentioned in the fiberglass thread from the other day.
Other thing is all the 5200, pipe sealant, anti sieze compounds etc are stored in fridge to prolong life
Have both 5200 and lifecaulk brand new unopened.
Whatever it takes, i'll do, appreciate it, thank you

I don’t have much experience with 5200, but any single part adhesive like 5200 needs air to activate it otherwise it stays gooey as it was in the tube. When using RTV you have to let it start setting up before squishing parts together. You may have slapped those brackets on too quickly.

Also, you cleaned the parts with acetone but what did you use to clean the acetone off with? Acetone is used to clean up adhesives so if there’s the slightest residue on the parts it’ll actually turn the glue to mush.

Thank you,
I thought acetone was the end all, didnt know it had to cleaned as well, what cleans it off ?
Yes, schlooped on and put in place right away,
then tell the help "hold this and dont let it fall off or the bolts slide out while i go inside and put the nuts on"
Help was used only on the kplanes and steering mounts since the nuts and bolts cant both be reached,
but it ultimately does fall back on me, and how or where i failed.

Wash off the acetone with rubbing alcohol, which evaporated quickly, and give the adhesive a few minutes to catch some air and all should be good.

Rikuy didn't see you mentioned the alchohol, thank you.
Ran up up to publix and grabbed some rubbing alcohol and a canoli, all leveled out now.
Will let the stuff get some air before reinstall, may pull the grinder across the back to get some better tooth on it as well.
Thanks all.

I believe those adhesives are activated by moisture NOT air. They will cure under water.

I did a bunch of tests using 5200 on Aluminum. Never held well.

Now two pieces of fiberglass preped correctly not going to part them without chemical help.
