Water in Gas....AGAIN!!

[jwclbi]

Well for the third time this spring/summer I have a tank of real nice gas/h2o mix! And I have to tell you its really pissing me off! Now what i have been doing is pumping the fuel out of the bottom of the tank when the boat sits at the dock all night when its calm so it all seperates. About 7-8 gallons and that seems to work. But thats getting old and im only guessing how much to pump out. I have tried dry gas and really should have just bought rubbing alcohol because thats all it is and that didnt work. Any thoughts would be great. Thanks
