I am replacing the drain plug on a 2005 Gulfstream. What do I put to fill the hole behind the plug? It just feels like silicone now. It needs something more substantial.

My other question is: where can I purchase the 1/2" x 1/16" or 1/8" black ribbed weather stripping used for the drawer seals and behind the dash panels, etc.? The only thing I can locate is about 3/8".

Thanks in advance!!!!

Do you mean you are replacing the garboard FLANGE? Unless you dig out and clean/strip all of the silicone, most sealants will have trouble adhering. Something like BoatLife Lifeseal will work, though.

Do not use anything like 3M5200 - that's super glue and not needed for a case like this. Truthfully, any good silicone will work just fine - this is a mechanical attachment and the sealant is only used for sealant purposes, not glue.

Can't help on the seals - but try Mcmaster Carr. There's probably a few things that could work.
 
Just search on MD auto and Marine weather seal. Available at Amazon or Home Depot comes in two sizes. I have found uses for each size on my 330.

Thanks for the response. I am actually referring to the hole that goes through the hull. Past where the plug actually screws in.
 
Not trying to fill the drain plug at all. I ended up using a 1" brass through-hull tube and 5200 to make everything water-tight. to the back of the drain plug. Before it was a hole that was coated in silicone to keep any water out of the transom.
 
the transom is thicker than the drain plug flange is deep, so it only goes partially through the transom, not all the way. that leaves exposed wood.

when i replaced mine, i left it as it was. it lives on a trailer and i figure that area can dry out when not in use. if you really want to seal it up, i would clear out all caulk and then saturate all around with resin (without building it up). let that cure, then replace the fitting.
 
Oh, well that explanation makes more sense! When you said "fill the hole", it didn't make sense.

Truthfully, leaving it bare isn't a big problem since if it gets wet, it will always dry out. Unless, of course, you leave the bilge wet.

As long as you are 100% sure it sealed, though, you're good. Otherwise, any water that leaks past will stay there and migrate further up.

If you decide you want to redo, m y suggestion would be to redrill the hole a little bit bigger, fill the hole with epoxy - leaving a small tube/hole in the "dam" that you create so you can keep filling as it soaks into the wood. Then come back and redrill your hole. That hole will now be 100% waterproof and the wood will also have soaked up plenty of epoxy into it, as well.
