The boat began to stall when in idle. Then it began to die after a few min. while in idle. I was told that i needed my upper part of carb cleaned. Instead i added fuel treatment and then it started again so i changed plugs but no luck. I cranked the boat up today and it would die after a min. Now it will not even start. It does turn over/crank but will not fire up. One very important thing to add is that my fuel flip up cap has been broken so i have caught it open a few times when i am pressure washing boat. Could I have gotten water in fuel? If so, what should i do?
