I have a 2006 Yamaha 115 four stroke with just over 500 hours on it. About a month ago it started sputtering as I was idling out of the harbor (after about 5 minutes of idling). I checked the racor filter and it was full of water. I cleaned it out and replaced the filter and it ran great for about a week. Then it started fine but as I was idling out of the harbor it started sputering again. If I give it throttle it runs fine until I shut it off. Once it's warm it just doesn't run right. It feels like it is running out of gas. But if I let it sit for 8 hours or so it will start and run fine. I checked the internal fuel filter and there was a little water in the bottom but the element seems fine. Has anyone had this problem before?
