I'm with David on this one. Why do you think it needs replacing? My tank better last 20+ years! You can do a pressure test if you think its bad.

It’s basically a proactive measure at this point. The center console is out the tank access hatch is out. Perfect opportunity, or so I thought.

I have ordered this product:

Un-hesive 3M 5200 Sealant and Adhesive Remover,

We’ll see how this goes once it arrives. I’ll keep you posted.

Well I do understand there is no time better than now to see what you have. And either way you will not have to wonder did I make a mistake.

The above product for 5200 removal really works! Day 1, lowered the trailer and sprayed the release agent along the back of the tank, and let gravity do its thing. Day two raised the trailer all the way up and sprayed along the front of the tank and again let gravity do its thing. Day three using the same small pry bar and a block of oak that I tried moving the tank with before spraying the release agent, and boom, the tank popped free of the sole like a cork. Within10 mins., the tank was completely out of the boat. No mess as the sealant stays in tack, just scrapped off the tank bottom.

Tank is in good shape, other than lots of grime and some mold under it. Good to go!

I'll have to get some of that if I ever need to remove a 5200 sealed anything. Cool!

Did the unhesive eat a hole in the boat?

Make sure and neutralize it!

It is great you found something that works on 5200 and shared it with us.
I am glad to hear the tank came out with no problem and it is in good shape. Just goes to show if they are put in with good drainage they can last a long time. And now you will not have a tank worry in the back of your mind. Having no worry makes the time and effort all worth while.

Fallguy, no holes eaten in the boat. This stuff is water based, cleaned up the small amount left behind with a soapy rag. Interestingly enough, the product smells like 409. Now, on to the transom.

Have posted this before elsewhere, but a great tip I learned from my marine Fabrication buddy is that WD40 is a miracle cleaner on 5200 and 4200 before it sets. A paper towel with it on it wipes up any squeeze out or drips beautifully.
