Twice now I have gone to use my 2001 Mercury EFI 200 and I get the alarm and red light that means water is in the gas. We started pumping some into a bottle after fueling to see if it was from the gas station but it comes up clean. My boat spent some time outside while it was at the shop and the gas is now watery. The first bottle we pumped out was almost half water. Could rainwater have found it’s way into the tank somehow? Last time I had water in my gas the boat had spent a little time outside too.
