Suzuki DF150 Water in fuel error code

[Prubaby09]

My engine was Idling at my slip and shut down. It would turn over but would not start. Asked a mechanic and he said that the blinking rev light indicated i had water in my fuel. I dumped my inboard tank, refilled with fresh 90 octane NE, drained the VST, drained the fuel rail, drained and cleaned the fuel filter. Rev was still blinking so I replaced the fuel filter body with then sensor and still have the blinking red light. Spark plugs, oil filter and fuel water separator all have less than 20 hours. Any suggestions on what to look for?
