Drain plug?

[buck3]

All right I am getting ready to launch my boat for the summer and I am probably over thinking this.

BUT, what is the best drain plug to use for a aluminum boat.

I need a expanding 1" plug, not threaded.

I have looked around and see that they make them out of stainless, brass, and aluminum.

Mine is brass with a rubber sleeve & is tightened/ expanded with a mini threaded t-handle. Works great when I remember to use it There is also the same style that has a flip latch type handle on the end.

Yeah. I usually use the brass t-handle pug, I have just been over thinking the whole thing I guess.

Just got done going over my insurance and realized how much money that $1.99, made in Taiwan, plug keeps floating.

Don't use the snap handle type, someone gets a heavy leader caught up in it and gives it a jerk that snap handle could easily pop open. SS twist to expand better in my opinion though a threaded pipe plug made out of aluminum is the best if the hole could be tapped

The Brass one needs to be new when you launch the Boat. Replace it after two months or so if left in the water. I had my old NR's Plug go bad after a month in the water. I pulled the plug and the threads on the inner bras plate where eaten away. It was a plug that I bought a year previous. Red the stories on the Hull Truth and on BD. Boat sunk at Westport 2012 new boat and a new plug on Float 4.

I have welded in Aluminum pipe fittings with plastic plugs installed. and I do change them out now yearly.. $2. cheap. Better than a .

Had the same problem with the ss store bought plugs, gone after a month or so moored in salt


ended up bonding the plug bolt to the hull and couple boats later I am still good mooring the in salt

Maybe a stupid newby question, but why not an aluminum threaded plug in an aluminum threaded hole? Wouldn't use of the same material prevent bi-metallic corrosion?

Its not a stupid question. Some boats don't have threaded holes for a pipe plug so those owners need to use some type of expanding rubber plug. Those of us who have threaded holes use either stainless or aluminum pipe plugs.

Another option if you have a threaded drain hole is to use a heavy duty plastic pipe plug - no corrosion issues with the plastic plug. Been using one for 6 years with out any problems.

I would suggest, that if your hole isn't threaded that you take the time to thread it, or take it to someone qualified, and have it done. That way you don't have to worry about the plug falling out or failing.
