Pontoon drains

[DBeve]

I have a 1990 20’ Smokercraft pontoon boat, need to know what size drain plugs it should have in it.

most pontoon logs do not have drain plugs. however plastic vent caps at the top. you need to siphon out any water

Thanks for responding, but this old smokercraft pontoon has them on the rear bottom of each log and it seems the logs are filled with Styrofoam

That being the case (full of foam), I would open the plugs and leave them open until getting ready to launch the boat again.

Don't you currently have plugs? If they are threaded, head to any home improvement store and pick up plastic or brass plugs to match. If they are rubber expansion plugs, any store that sells marine stuff will have them. They are adjustable for size.

Yes but they dont seem to fit properly, I was going to just silicone them in but figured I would try finding the correct size first, but have not found anything regarding the plug size. But thank you for your help.

Some time ago I had my aluminum welding guy fit blocks and plugs to match. We used NPT threaded Brass plugs with PTFE thread tape.
Is it possible that you need NPT plugs.
