Default Yamaha 200 Carbs drain ports ?

Saludos !

My boat has a serious problem with water in the tank, which leads to dirty and clogged carburators. I am tired of removing the carbs and cleaning them, so I`m looking for solutions to this. I cleaned the tank completely dry, found half a gal of H2O in there. I know is from condensation because when I gas the boat, a lot of water spits out of the air vent port.

Last time I pulled the carbs out, noticed that they have what seems to be a place to put drain fittings on the carb fuel cans. See photos.
I am planning to drill and tap for either fittings with hoses, or at least screws, so I can completely drain the carbs on my Yami without removing them. The 13mm drain bolts on the sides do not drain all the fuel out, they are only ports for the removal of the main jets.
Has anybody seen anykind of drain fittings on this carbs, OEM or mod.
I am planing to use fittings like the ones used on model airplane engines muffler-pressure fittings.
Any suggestions ?
