re: Help - Boat Corrosion at Drain Plug

As long as you have dissimilar metals, you’ll have galvanic corrosion. I’d go with a traditional/old school expandable rubber plug (or else the threaded plug shown previously). Other option is to keep all your dissimilar metals painted/coated, so the water/electrolyte can’t enable the corrosion.

I’ve used a rubber plug for years without leaks.
I change rubber plugs every five years or so and I keep two spares on the boat.
They are cheap so when I do change the plugs I change the spares as well so 2 out of the 3 plugs get thrown away without ever being used.
