Working on getting my boat in the water for the 1st time this year. I have a yamaha 250 4 stroke built in 2006. Went to start it and I have an alarm going off. It's only beeping in neutral. Stops as soon as I put it in gear. Manual says it might be the fuel/water seperator. I have taken it off and drained it. Didn't see any water in it. When I disconnect the sensor on the water seperator, the alarm stops. Where can I take it from here? Thanks in advance. Looking forward to getting on the water.
