just got boat and for 2 days boat ran fine. third day ran good for couple hrs then slowly started running worse and worse. wont idle and runs really bad. we changed the spark plugs the fuel filter and cleaned the air filter. we have a fuel pump on order. any ideas on what it could be? relay?? is there two filters? is there 2 fuel pumps??
