My boat has been sitting for a little over a year. With the ethanol problem was thinking of getting all the old gas out before refilling it. Thought I had about 5-10 gallons in it but it looks like I have closer to 40. Took a picture of the gas I took out (just 5 gal). The bottle with the yellow on the bottom I took out first the blue gas came out at the end. I took the gas from the bottom of the tank. Any idea what's up I thought gas was yellow and water was heaver than gas. Expected to see water. Also I do add oil to my gas. But wouldn't that separate from the gas too?
