Ok, I see a lot of posts like mine here, but I have a very specific question however:<br /><br />I have a 1989 OMC Cobra 5.7 V8. I suspect I've got water in the fuel tank (will confirm that tomorrow). Let's say I do have water, there are a few gas additives out there that dissipate the water, the question is - which one is the best? I suspect my water comes either from condensation (winterized it with the tank half-full, or the bad gas that I bought off of the marina on my last trip last year and they had a pump issue right before that). I now have about 150 litres of gas in my tank and I was hoping that I don't have to dump it.<br /><br />Thanks in advance guys.
