Hugh,

Just a note, your water pump may or may not be fully drained, as the
impeller creates several chambers within the pump and only one or two
would drain when you pull the plug.  If you're not going to run
antifreeze through it, you may want to loosen the drive belt and rotate
the water pump by hand to empty it.  

I haven't really considered the issue because I generally run
antifreeze, however if you are not, you may take a look at where water
might not have drained from pulling the three plugs, e.g. the raw water
intake hose, the thermostat housing, muffler etc., and also because the
water is draining from a more or less closed system, you may want to
pull a hose or two off it's connection on the top of the engine to
ensure you don't have a vacuum holding water up in the system somewhere.

Last time I listened to mine drain, it probably only took a couple
seconds to empty what was readily flowing.  No idea on the volume
though.

Andrew

Good day,
 
Thanks to Mike, Andrew, Bill and Brian for your help and advice.  I was
able to locate all three drainage screws with no problem.  Having found
them, the challenge was finding a short enough wrench to fit in the
spaces.
 
The drain screw on the water pump is at the 7-8 o'clock position and
there is barely room to get in between the screw and the edge of the
flywheel.  Fortunately none of the ports were blocked with sediment and
the water drained freely.
 
Just out of curiousity, how much water is actually contained within the
block when the passages are all full?
 
Cheers,
 
Hugh
