Went to the lake to winterize my pontoon boat and boat ran good until the way back. At full throttle it seemed to all of a sudden act like it didn't have fuel. Pulled it back to half throttle. Felt the bulb and it was full but not hard. I pumped it at first to keep the motor running but then I let it go and ran it back to the marina at half throttle. Made it. Winterized the fuel for about 15 minutes hoping the mixture made it all the way to the motor. It stayed running until I shut it off. Any thoughts? <br /><br />Thanks... Gary
