I have a recurring problem of water in my fuel tank for the past year. I have ruled out condensation, ethanol absorbtion and sending unit leak. Pumped 2 gallons of water out of tank this weekend before gas started coming out. Boat is a 2004 Angler Grande Bay with a 200 Yamaha Saltwater Series. For 3years the boat was fine and then all of a sudden I have water in tank about every other time I run boat. Once I get the water pumped out the boat runs fine. As far as I can tell there is no external fuel tank vent other than venting through the fuel tank cap. Wondering if there is a vent hose sitting in bilge somewhere but access is very limited and trying to avoid pulling up console. Anyone else had this severe of a problem or have any input? Really want to get this solved before venturing offshore this summer and have engine troubles.
