I have a 23' 1995 Parker with a 150 gallon aluminum tank. A month ago the engine stalled - result was I had bad gas. Had the boat pulled and professionally pumped out. FIlled the gas tank back up with fresh tank from a Gulf station (high volume place on the road) and then put boat back in. Had carbs cleaned and boat ran great. Last weekend boat wouldnt come up on plane and engine stalled when I gave it power. I checked fuel filter and it has water in it again and a bunch of small white particles that settle on the bottom. I called the gas station and they assure me they get fresh gas deliveries and have water alarms. No way its sabotage as I have no issues at marina and its security protected. Gas cap is sealed and seal is fine. No leaking gas in bilge or water in bilge. Vent is sound and facing down. I am at a loss of how water is contaminating gas.....any ideas?
