Just got back from a 12 hour drive to Tennessee where I picked up an 83 ss with the 440. Shamrock hooked me up. I have stripped the inside of the boat and discovered that the foam filling between the stringers is saturated with water. I cut the fiberglass floor out and am trying to decide wheather or not to tear out the wet foam or try to dry it out. I found the thread about replacing the floor but could not find anything on tearing out and replacing the foam. So... tear out the wet foam or try to dry it out? Thoughts?

I am having the same issues with my 83 I am restoring. The foam is completely saturated. I would like to know the answer as well.

What foam? I own a boat four years older and the only foam in under my gunnels.

If it is satruated with water, I would get rid of it........

I pulled mine (there was ALOT of water in it) and replaced with great stuff spray foam which is probably now saturated too. TB

The foam seems most saturated nearest the injection holes. They were all cracked and open for water to get in.

The stuff will never dry out.

When they went to fiberglass stringers in 83' they used foam in between. I guess as a dampening system??

I think I would first find out where the water is coming from for sure. Around the injection holes, but how is it getting there? Don't want to replace foam and seal everything up only to have it saturate again.

I am sure most of the water came through the injection holes but I did find a crack under the fuel tank near the exhaust outlet where the floor is glued to the hull. I will fix that crack with some 3M adhesive. I tore all wet foam out, have you ever seen the show Dirty Jobs! While everything is drying out I cleaned the bilge with degreaser and checked all the wiring for worn insulation.

Any thoughts on what to use to refoam the hull?

I've always wanted to try ping pong balls... they won't absorb water, would be easy to "inject" into closed spaces, and could easily be removed if you ever need access to what's under them. Not quite as effective as foam for floatation due to the space between them, and I'd have no idea where to find an affordable source. Thankfully (?) my '79 is lacking any foam under the floor. Probably would sink like a rock if ever holed, but easy to drain!
