Help - Leaking Water

[KDF2020]

I have a 2003 MSX140 and have found where its leaking water.

The through-hull bearing that mounts to a sloped metal casting, that is bonded to the hull has de bonded itself.

What do I do now? Has this happened to anyone else? Any tips (or products) to rebound it and seal it water tight?

According to the parts breakdown for "drive system" it appears the through hull seal bolts to the hull.

Pirate33 had the MSX through hull base casting de-bond from the hull years ago.

He posted how it was repaired.

here is a picture to help clarify. There are not any fasteners on it.

I was able to dig up that old post but I did not see any details on products used or if he took it in somewhere.

My first attempt was a some 3M marine sealant and some epoxy but that did not hold. I am having a hard time finding the right bonding material that want to stay adhered to the aluminum cast. Any suggestions?

Might try to fiberglass wrap the casting once I find a better sealant/ bonding material. Again open to any suggestions.

I'd suggest you PM member bfarnam. Brett is very knowledgeable about different adhesives, especially 3M products. It is kind of crazy how many different variants there are of adhesives. I'm not sure what I have more of, tubes of different types of adhesives or tubes of different types of Loctite.

The bearing/seal housing bolts to that piece.

That part shouldnt have alot of force on it, Make sure the bearing/seal isnt trying to lock up.

Thanks will do. Started looking at more of those products and got overwhelmed haha.
I hope to follow up soon with a working solution.

Find Plexus AO420...... I know that "On Hand Adhesives" sells it online.
Contact Mark Cipolla for advice.

WOW the PM notification got REAL lost in my inbox.

Did you ever find a marine structural adhesive that worked or do you still need a recommendation?
