"Hi everyone, I'm new here

"Hi everyone, I'm new here. I have a 1997 Yamaha 25hp 2-stroke. I had left my boat sitting for about a month or so, (hurricanes). I went to start it up, it cranked just fine and ran like a champ. For about 2 minutes. It dies under throttle. I noticed that my fuel ball was soft. I gave it a few pumps and cranked it. It started up and ran strong, but would still die under throttle. I replaced the fuel line, fuel ball, fuel tank. I also cleaned and inspected the fuel filter, all 3 carbs, and fuel block. Even after all of that, It's still doing the samething. I'm at a loss. Can someone give me any insight or ideas to try? Thanks!"

you could have a bad fuel pump, air leak in lines, wrong float height"

"Upon checking everything out and testing different pieces, I'm getting air in the fuel line from the pump ball to the fuel tank. I have it narrowed to the brass QD fitting and the hose barb on the ball. Thanks for everyones help!"
