R25 Garboard Drain Plug Replacement

[RLFleming3]

We recently purchased a 2016 R25 and somehow the garboard drain plug is missing. I've searched online w/o success. I measured the opening at 3/4" and ordered one, but it's slightly too big. Most plugs I see online state 1/2", but that can't be right. The nearest boat store is over an hour away, and when I look at their website, all they show is 1/2". It seems like these should be plentiful and easy to find, but so far it has not been. Would appreciate some help.

Okay, I figured out the 1/2" is for the NPT (National Pipe Thread)...I'm learning.

Hello, looking back at our bill of materials we purchased those from King Marine, PN: 86500-1. It is listed as a 1/2" plug.

Kenny has you on the path to the correct part, but there's still the issue on why a 1/2" plug is going to fill a 3/4" hole...

The thread on the plug is 1/2" NPT (national pipe taper or national pipe thread...depending on who you're drinking with when the topic arises). The size of NPT pipes are stated by the inside diameter, so a "nominal" 1/2" NPT pipe is actually .084" on the outside diameter.

Confusing as all get-out.

Any 1/2 pipe plug will work for an emergency, but you need the correct one very soon to avoid corrosion. I use a key float on the ignition key ring that opens up so you can put the plug inside the float when not installed and you know right where it is. These floats are easy to find. Amazon "boat key floats". I also have one in my tool box. 😉

Thank you all for your responses. I feel confident that I'm on the right track now.
Personally, I always leave the drain plug with a boat, even on the trailer, but somehow in the transition from the previous owner this one went AWOL.

Having the right 1/2 pipe plug for emergencies is crucial to prevent corrosion. Using a key float on the ignition key ring ensures easy access and storage. Amazon offers various boat key floats for convenience.Insta pro

I store mine in the swim step cavity when they aren’t installed. Handy, and in the same place every time.

You are all using bronze garboard plugs right? See other recent post on why not to use brass below waterline.

As stated, any 1/2" plug will work in a pinch, and even if you are trailering, its not all that important...but, if you are leaving the boatb n the water for any time, or leaving the plug in for a long time, the plug should be bronze. A lot of the plugs, even i with bronze fitting, are brass. It's all in the small print.
I still have a brass plug that is virtually welded into the bronze garboard fitting that was originally on the boat. Had to remove whole fitting and replace.
