I have a 2007 Yamaha 60 hp 4 stroke outboard. While at the lake I suddenly lost power, I later discovered that I had gas in my oil when I checked the oil level. I also found that I had a bad fuel pump. I replaced the fuel pump, changed the oil and took it back out, for about 30 minutes it ran fine then it lost power again and I still have gas getting in the oil. I am also loosing fuel pressure in the line from the tank to the motor when running. When it is not running it does not loose pressure at all even after a few weeks of sitting. I am planning on taking it to a mechanic but wanted to see if I could find some more info here first. Thanks.
