edit this whole part, if the tank only has a few gallons, say 10 or less draining and throwing away that fuel might be worth it in the long run. whats 30 bucks in the long run. just watch as most tanks have an area that does not drain to allow the crpa to settle. if you are going to trash the fuel when you get down to just a few gallons get a bunch of people to rock the boat for 10 mins to stir it up to get the most junk out... end edit
if you racor is lower then the tank you could just open the drain. if its not go to an auto parts store and get a small electric fuel pump and use that to pump it out thru the line to the racor. or even a fuel bulb for an outboard will do it. even one of those electric drill mounted pumps will do fine
the faster you get it out the less long term problems you will have. if you use a electric pump, or the drill mounted one. drain as much water as you can, then hook up a cheap water separator filter and use the pump to run the fuel thru the filter then back in to the tank. do this a few times and then add biocide to stop any growth. then dont keep filling the tank, let it get down to 1/4 full before you fill it again
for the separator use one that takes a spin on carterage that you can throw away. change it a few times as it runs, and run it for a few hours. ie poor mans fuel polisher
