14' aluminum boat, need drain plug

[JaCrispy]

Buddy of mine just picked up this old Duratech and I need to install some sort of drain plug in it. Any preference to what style to use? 5200 for sealant? Thanks.

I wood just go to Walmart and buy a $2.00 drain plug. Buy two so you have a spare.

I understand what your asking for and I would certainly go with a standard 1" (ID) threaded through-hull METAL type drain. And apply some 5200 around the threads and install. I don't trust any plastic drain but that is just me... JMHO!

Any problems with what metal to use, brass or stainless? I would assume stainless to be safer on the aluminum. I'dd through bolt it with SS machine screws and lock nuts on the inside of the hull.

I installed one of these in my 14' aluminum boat.

I bedded it in JB Weld, and attached it with stainless steel machine screws and nylock nuts. It's been holding up great for several years, though tough use up in Ontario.

I'm sorry I miss read. To install one I'd use brass and do as above.

They do make aluminum drain tubes, if you want to keep it original.

It does require a flaring tool to install properly, or...You can make your own.

A word of caution here.....do not use brass and aluminum together. These two metals will cause electrolosis and the aluminum will get eaten away. Some have had limited success by using a barrier between the two metals but with time the aluminum will weaken and dissolve. A chemical reaction will take place so for aluminum please use stainless steel, unless the brass has a heavy coating of chrome on it but even then.............
