Boat flooded full of water concerns.

So my trailer blew the spindle and tire fell off etc after repacked bearings say 500 miles on them, and ruined the trailer. Had to flat bed it home. So with no trailer and funds tied up in buying a house I had to sit and wait, so I covered it, and planned on finally winterizing it 2 weeks later after my vacation. No freezing Temps yet, thank god. So heres the catch. A small but robust log somehow ended up on my cover and left a divet, this in turn made it fill with water. And at some point it burst......a lovely plastic bait bag and some other random object clogged the drain plug hole. My boat had easily 2 feet of water in it, drained for 15 minutes non stop,enough to almost cover the batteries and submerge my dual pro 10 amp 3 bank charger(supposed go be waterproof), my tackle storage stayed dry, but my rod locker was full of watee =( i turned the bilge on to speed up the draining and it turned on, and the master switch worked. My boat doesn't have an auto bilge. 1990 nitro 175 tf. What am I looking at for damage? 

 

BTW this is a repost from the electronics forum.

The biggest thing you have to find out is, does the boat have open cell or closed cell flotation foam.  In the year yours was made, it could be either but a large number of them was still using open cell foam.   If it has open cell foam and it sat with water in it for very long, the foam will absorb water deep into it and it lets it in a whole lot easier than it lets it back out.   I had an 1989 Stratos that had saturated foam.  It was always kept under a shelter after I bough it and nine months later, when trying to figure out what it's performance was still so bad with a new, larger motor on it, I checked the foam and it was totally saturated.  I finally took the cap off, pulled the floor out and dug all the foam out.  five gallon buckets full averaged 28 pounds each.  I pulled out 300 pounds of wet foam.  It took 56 pounds of new (closed cell) foam to replace more than I took out.  Plus I had to replace one rotten stringer.

So, pray yours has closed cell foam.  With it, only about 10% (the outer layer) of it absorb water and it's able to dry back out after a few months of keeping it dry.

Open all the storage lockers and dry out using fans. Spray all the wire terminals with a product called DeOxIT. Hope your boat doesn't have a glassed over wood transum, that could dry rot.

The closed vs open cell flotation foam could be a nightmare!

Good luck!

It appears to be closed foam, and u don't know about the transom, it has a 150 hp Johnson on it....hmmmm.

So as I feared I have open cell foam.....also the floor is soft.....a buddy came out and tested the transom (tiny drill bit test ?), said it was sound, but the floor is rotted and when the floor is rotted expect a stringer to be rotted....
