Ok thanks guys for the replies. I always thought thru-hulls prevented ANY
water from coming up through them. But all my below water line drain hoses
have at least a few inches of water in them.

So it seems
that 4-5 inches of water is nessary to keep the through-hull from letting
water in. Is this normal? Because if so it means that the little metal
bands holding the drain tubes on to the seacocks are the only thing
preventing the boat from sinking, and that seems a little scary.

================================

As others have pointed out, it means that your seacock is 4 or 5
inches under water (not unusual, especially on sail boats). In
addition to the metal bands that keep the hose from slipping off, you
should also have two stainless steel hose clamps. That is what REALLY
keeps the hose from slipping off. All underwater hoses should be
double clamped.

Next time, close the seacock before removing the hose. It's a good
opportunity to find out if everything is lubricated and working
properly.
