Removing soaked Foam and keeping solid deck in tact???

[tmyers]

Alright so I have wieghed my vessel and it seems she has a few hundred extra pounds.
She has a solid deck and the transom is strong.  
However, the other day i was thinking of a way to get the foam out with out redoing the deck, and thought of an idea.
Is it possible to redo do the transom from the out side and in the areas of the stringers and the areas outward toward the hull.
1. cut  access holes and use an auger to drill out the soaked foam.  or some sort of small post hole digger.

Please let me know if anyone has done this or if it may work.
Thanks,

Hi!

Depending on the hull length, you'd need a well-drilling bit  And the stuff doesn't just drill out...it has to be physically removed.

If its just a couple hundred pounds...no biggee....keep running

What model and size Aquasport do you have?

Oh yeah got it.

Why not tape up and apply a vacuum to drop pressure and evaporate water from foam?

Have you actually drilled holes into the stringers to see if they are wet?
I was sure mine were wet until I drilled them the other day and got dry powder and not a hint of seepage from the holes after 4 hours. Your weight might be from the deck itself being wet or the foam on the outside of the stringers. With your Ttop and setup they might not be wet at all.
Now to answer your question about drilling them out. You can do anything you want. The problem is the stringers at the aft end have a step down about 18 inches before the transom. They are not full height all the way back. So, to drill them out you would be limited by this height issue and would not be able to reach the upper portions. The other problem is if you had a access hole on each side you would need to tab the repair from the inside as well as the outside to maintain structural integrity. This would be VERY difficult to reach and do a proper repair.

You need to find out where the water is coming in from....a common point is thru hulls...they need to be re-sealed every 5-6 years. Clean and remove old caulk, silicone, etc. and  reseal with 5200.

 Couple weeks ago I bought a boat.....noticed a rust stain on hull coming from drain on fish box....pulled off clamshell cover and water ran out of screw holes. Called the factory ( hull has lifetime warranty) and was advised to cut out a 6 inch hole in bottom of fishbox, remove foam and remove water. After removal, inspection plate with screw on cover and gasket and seal with 5200. The forward area by the keel is a sealed bulkhead in front of the fuel tank.

 Using a shop vac, I got out approx. 10 gallons of water, the tough part was chopping/digging out the foam. After leaving it open, boat lives in the shop, remaining foam was completely dry, put a damp rid container inside the hole, after 3 days, no moisture, crystals were dry.

Re-sealed ALL thru-hulls, 100 miles on the water and 6 hours running time later, Appears good to go.

No i havent drilled any inspection holes in the stringers yet.  I have put a moisture meter on the stringers and it says there is moisture.  How much i dont know.
I thought it would be difficult to do the repair on the transom after the foam was taken out.
I need to just drill the inspection holes and see what i really have to deal with.
As for the tape and  vacum techniqe has anyone tried this?
Thanks

Just went through your other thread.

Yep, the old girl is just like the rest of her sisters, she's put on some weight. I know you don't want to hear this, but the only way to do it right is to take a skilsaw and have at it. You'll never get it out by suction, as you can't access the stringers through the transom as Slvring explained. The effectiveness would be questionable even if you could.

I agree with gran that you will need to tackle this from above.  Also, even if you somehow could get all the foam out from the back, what are your plans after that?  Leave it out?  The fiberglass sides of the stringers in my '67 22-2 are pretty thin.  There is no way I would trust them to support the deck/console/people/etc without some foam inside to lend some structural support.  And from what I understand, unless you stood your boat up on its bow, you will not be able to get the foam to fill the forward areas before it expands (if you are pouring it in at the transom).

good morning!

So, if your girls put on a few pounds, my girl had type 2 diabetes and would have needed a forklift and a wall removed from her home to be taken to the hospital. I digress, the stringers were soaked.

I agree, there is only one real way to do this, and it's the hard way. If your deck is good as well, I really wouldn't worry about it. When you pull the deck up, there is a good chance the bonding cement between the stringers and the deck will destroy the deck as you remove it. If you look back at the blog of my build (in my signature), you will see that doing the stringers....well, sucks.

It's an enormous amount of work. I would suggest inviting skinnier people on your boat:)

Alright so I have weighed my vessel and it seems she has a few hundred extra pounds.
Thanks,

That doesn't sound like a lot of extra weight considering you have a T-Top adding weight and wind resistance, the 115 motor doesn't sound like enough HP if your trying to get to 40 mph with that setup.
You live in Florida, take the cover off on sunny days and boil any water out

IMHO, I would run her and look for a good deal on a 150hp, especially if you have solid floors and Transom
The brochure http://www.classicaquasport.com/gallery/showphoto.php?photo=2724&title=as-19-6-brochure2-c1970s&cat=554 says a 125 OB will run her at 39 stock, out of the factory, 85 OB at 33mph......

OH YEA.....PICS Please.....
since this was a I/O to begin with...

I have a 72' 19-6 with a F115.   The boat used to be an i/O.

maybe the OB isn't adjusted correctly for the hull
