Sea-Dog Nylon Screw-In Drain Plug, 1 Inch | 520010-1
Sea-Dog Nylon Screw-In Drain Plug, 1 Inch | 520010-1 — Product description
The Sea-Dog 520010-1 is a 1 inch nylon screw-in drain plug for your transom. It threads straight into a standard garboard drain fitting, so you can drain the bilge on the trailer and seal it back up before you launch.
Every boat needs a drain plug you can trust, and this one keeps it simple. The Sea-Dog 520010-1 is a molded nylon plug that threads into a 1 inch transom drain fitting. Pull it on the ramp or back in the driveway, let the bilge drain dry, then screw it back in before you launch. That's the whole job.
Nylon is the right material here. It won't corrode, it won't seize up inside a brass or aluminum fitting the way a dissimilar metal plug can, and it shrugs off salt and freshwater alike. The threads run clean and snug up by hand, so you're not hunting for a tool at the ramp with a line of trucks behind you.
This is a straight replacement for the common 1 inch garboard drain plug. If you've lost the one that came with the boat, or the old plug is cross-threaded and weeping, this drops right in. And it's worth keeping a spare in the glovebox. They're cheap insurance, and you don't want to find out you're missing one after you've already backed down the ramp.

Frequently asked questions
What size is this drain plug?
It's a 1 inch diameter threaded plug, sized for the standard 1 inch garboard drain fitting found on most transoms.
What is it made of?
Nylon. It won't corrode, and it won't seize up inside a brass or aluminum drain fitting the way a metal plug sometimes can.
Do I need tools to install it?
No. It threads in and snugs up hand-tight, so you can pull it and put it back right at the ramp.
Will this replace the plug that came with my boat?
If your boat uses a standard 1 inch threaded transom drain, yes. Just confirm your existing fitting takes a 1 inch screw-in plug before you order.
