What's the correct brass drain tube size for a classic 15, I see there are 2 different size on whaler central article but they don't specify and can't find the correct size for my application by doing a search. I'm assuming is 1", I'm I right?
Planning on buying this flaring tool https://www.amazon.com/gp/product/B0082ANA0C/ref=ox_sc_act_title_3?smid=ATVPDKIKX0DER&psc=1
If it's the long one that's about 15" long, you'll probably end up with 1" x .030 wall brass tubing, while the standard drain tubes you buy are .020 wall. To form the .030 wall tubing, heat the end with a propane torch until it's a dull red, then drop it into a bucket of water to anneal it. Also apply a little grease to the tube to help it form the radius. If done right, you should have almost a half circle on the end and will hold a 3/32" x 15/16" or so O-ring in place against the outside of the hull (in addition to 5200 sealant).

Thank you very much for the detail, will definitely do that as I have the torch, just need to order the tool, I'm ordering a 6' tube as I have 2 whaler 15's. I did this a long time ago and I remember I didn't do the annealing process and one of them broke, this time I'll do that.
I'll take this one step farther and suggest using the flaring tool with an air chisel to form the ends. I've done this on a 13' sport, a 15' sport, a 17 Montauk, an 18' Outrage, and a 22' Outrage so far.
I use an 8 pound sledge hammer to back up the tool against the pre-flared end, use an old cut-off chisel to form the flare on the inside of the boat. You should be able to get O-rings on both ends of the tube.
