Re: Install drain in Aluminum boat
you use a hole saw available at any home improvement store, you put it in the drill and drill the hole. then you put sealer on the inside and out side of the hole, insert the tube and put the nut on the inside, and tighten. that simple. then you put the plug in it. i prefer the thru hull and you can count on it not leaking, i don't trust just 2 screws.
