If your going to replace the manifold, then you could drill and tap whatever size you want when it’s off. A pain yes but a proper job
another idea is make a bespoke tap and blank. get a length of silver steel, machine an npt thread form onto it but slightly oversized. Cut a couple of flutes and harden. Tap hole out in situ. Machine an oversized plug to fit and seal with your choice of sealant.

It is only a temporary repair, need to move the boat about 5 miles to haul her out. Then she is getting a major upgrade.

Tapered wooden plug, tapped in with a hammer, locked in with fencing wire. Saves wasting £5 on Liquid Metal

May I ask why it had to take until post #26 of the thread for you to share this nugget of information? Do you not think it might have been somewhat important to mention it in the initial post? People are spending their time giving you good, economic engineering solutions and finally we find out that all you want is a quick, temporary job just to enable you to move the boat.
Use a steel blanking plug to clean the thread out a bit, then use that or the brass plug with:
Thread sealant?

Or PTFE tape?
Or plain old silicone sealant should handle the temperatures involved.

I bought a box of taps and plugs to repair stripped sump plugs. Lots of sizes and several of each for £14 of t'net. Was going to suggest that. Soon as I saw it was temp, then Jerry's answer was spot on. Use an oak plug. (I muck around with boats and see this sort of thing often) All boats here are required to carry a set of tapered plugs to bung up a skin fitting if it fails.

That's always been the case on any boat that I've chartered. And usually any boat that I've sailed on. Self preservation.

For a temporary fix I would consider using use an expanding test plug, I've used them to pressure test radiators and oil coolers and other small sealed vessels.

Would have to have been an ginormous long and thin plug.
