I have a 2005 Stingray CS 220. I am afraid there is a garden of ethanol gunk growing in my gas tank. Took it out once in 2009 and had to call for help to get back to shore. Put Stabil in it that didn't help. I tried to siphon the gas out of the full tank, it would not siphon. Does anybody have a clue how I should go about getting the bad gas out of the tank. Boat will not start. Need to get all the gas out of the tank. Everything is as purchased from the factory. Can anybody please help me? If you live anywhere near Alabama and have the capability to do this, please get in touch. Thanks!
