Wood Rot- best plan of attack?

[Maj92az]

Few posts ago I asked about removing my glassed in seat bases in my 89 searay. As I preceded this morning i am finding a good amount of wood rot. Certain areas it dries up but some areas are black and the frame of this seat box crumbles. The plywood used under the foam (which was filled inside the seat bases) is level with the main deck. But it's untreated uncoated wood. No wonder it's rotten and worked from there. It certainly diddnt come from below...must of been from top. First guess was water filled the gas tank storage area which borders the seat base.

my queation is best way to proceed. I'll remove my box some more and see how far the rotten ply wood goes. It seems 99% of the boat is treated and sealed with resin I can't imagine how far it can go. For example it used the sealed ply of glass as a barrier.

any advice or tips or ways to inspect further. Thx

if the rot is just at the seat base, but if water is standing I imagine you will be doing like the rest of us, and replacing the floor and stringers. If the wood rot is limited, you can try WEST systems epoxy on Amazon or Progressive epoxy (epoxyproducts) which "claims" it can replace rotted wood.


Hoping your floor is not rotted. Good luck

Rot and wetness can be very deceiving. I'm pretty new to this, but for me in my own project, I went from thinking only a 4x4 section of my floor was rotted, to discovering all the wood in the boat was about rotted, if not on the verge. Also found standing water in pockets of foam, and under my deck. Water from last year, more than likely.

Point is, if things are rotted for whatever reason (say, somebody installed untreated plywood for example) it's likely other corners were cut during previous boat repair and you have more damage then you might think. Would be worth looking further into.

your boat is a 1989 SeaRay. the 80's were the heyday for slapping boats together and sending them out the door fast. you searay has slightly better construction than the 80's bayliners which rotted in the 80's

remember, boats were designed with a 15 year life expectancy, yours is now coming up on 32 years.

boats rot at the keel and work their way up. by the time it gets to the deck, many other things have rotted, such as the transom, stringers and bulkheads.

That being said, I highly suggest you read links 14, 15, 18, 2, 3, 4a, 4b, and 1...... in that order in the DIY link at the top of the forum. https://forums.iboats.com/forum/boa...r/295740-how-to-s-and-other-great-information
