Found water soaked wood surrounding the gas tank under the rear deck. Do I replace it or treat it as is with some chemical?

I've Heard about treating Rot with Anti-freeze, But i have no 1st hand knowledge of the results...<br />Replacing is the Only Sure-Fire Way to Stop Rot......

Get rot is such a product but you will have to dry it as much as possible first, once dry apply the get rot and it will make the wood harden then re-glass to stop re-penetration of water <br />Greg

I would recomend looking into it a little futher. I just redid a 1985 Sea Ray. Every piece in that boat ended up being full of rot. I think that what you will find out is that the floatation foam has soaked up all of the water and that is what is rotting out the wood.<br /><br />Just my .02

Is the floatation foam a permanent part of the structure, blown in? or replaceable. The floor stringers seem solid. I may dig a little deeper under the deck and replace everything if I have to. I like the style of the boat and the exterior is in good shape. Wiring is clean and very little corrosion around the boat.<br /><br />Thanks,<br /><br />Bob :p

Re: 1990 18FT SEARAY rotten wood

This question is for Big Dog but I'd welcome anyone else's input. I just bought an '85 Sea Ray and I also found the wood on the port side of the gas tank is rotted; the other sides seem ok (still hard when I put a screwdriver to them). There's a strip of plywood next to the tank, then a ~2" piece of wood behind it that runs the length of the tank and extends further toward both the bow and stern. Both the plywood strip and wood plank are rotted enough that I can pry off sections of them. What I see behind and underneath the wood plank (which is about 3" high by the way) is fiberglass; and this fiberglass feels solid. It seems that the plywood floor rests on top of fiberglass deck. Is that how boats (Sea Rays) are put together: stringers, then fiberglass deck, then floor?<br /><br />I plan to remove the gas tank and replace any rotted wood, including as much of the plywood floor as I can. Is there a way to find out whether the stringers are bad or whether the foam is soaked with water without cutting holes in the floor? Can I take advantage of the removed gas tank? From what I've read on this forum, it sounds like if either stringers or foam is bad, I'm likely to have to cut up the entire deck to fix them. This is something I would not be able to do; I don't have the time/resources. If it comes to that I'll have to sell the boat at a loss or give it away, so I'd like to find out. Thanks for any input.
