i have a 87 searay 22ft. with the 350 motor in it the problem is when i open it up wide open it will runs good for about a minute then it will cut out ,then pick back up . then cut out again. when i back it down to about 3800 rpm,s its ok . i,ve change the fuel filter in the carb, and the water fuel filter but same thing.plus today in one of the tubes from the valve covers it had some white oil in it very little .the boat has sat for about two years. i,ve put about 20 hours on it in about aweek and the oil is clean no sign of water . <br /> thanks and have a great boating summer<br /> bob moore
