It turns on and idles when out of the water i can give it gas but when i put it in the water it works for a second but when i get on it and give it gas it dies i also notice that it has a delay with the throttle response i sqeeze the lever and it slowly revs then it catches up and screams now i have changed my hoses and the filters in the carbs are clean now my question is this a carb issue or is this electrical what could cause my ski to shut off when it has a load
