Hi there and welcome to the wonderful world of boating. An outboard engine does not have any water in it, so it cannot be drained. There is a water pump inside the leg, just above the gearbox, (the torpedo-shaped part at the bottom) that is keyed to the shaft that comes down for the engine.
So, when the engine is running, the impeller inside the waterpump turns and lifts water up a tube, around the water jacket and cools the engine. The warm water is expelled through the exhaust. As soon as you shut the engine down the water stops flowing and drains back out.
With regards to the fuel in the carburettor, when you have finished for the day, with the engine still running disconnect the fuel supply and allow the engine to run until it stops. You now have a dry carb and no fuel will spill out.
