“Keyed” drain plugs?

[jnbwolf]

What are the options to plug these type of Keyed drain plugs? I have searched and can’t find anything. Normal plugs don’t seam to seal with the keyed parts sticking out.

I have a 2003 sv1900cc that has been tight with zero leaks and it has started to let in water the last few trips. Nothing major but I suspect a transom plug or drain pipe. I would like to plug all discharges and test.

Can’t seem to add a pic but the drains have 2 keys (square extrusions opposite of each other inside tube)
Thanks

I'd suspect a hose rather than the thru hull fittings it self but try something like a nerf ball to plug them.

I'd like to plug or remove all the through-hull fittings on my older 1900CC. Do not trust aging piping/o-rings, much less the seals on the through-hull fittings.

The 1" plugs I have on hand are too big. Wine bottle corks seem to fit a few fittings, and allow for a couple of clamps (*hic). Worked well for the transom fitting--which I'll probably glass over, eventually.

I'll have to find a few more corks to plug the (*hic) port and starboard fixtures. But might have to visit the liquor store to get more plugs...(*hic)....

a bathtub stopper works well for the larger thru hulls, but don't let that stop you from going to the liquor store...

I bought stainless plugs from these guys to plug my scuppers. Pricey, but last forever.

Really. A wine bottle cork and an O-ring are all that keep me watertight.

Pulling below-waterline fixtures and glassing over is coming up there on the list.

Do you have a picture of the drain plug? Is it SS and sits flush when tightened?
