I'm new hear and want to thank all in advance for any help I can get. I have a 2009 Baylinger 245 SB with a 5.0 Mercuiser. Yesterday I think I ran out of gas. When I came off a plane the engine wouldn't run above an idle and was very rough. The tow boat brought me 15 gallons of gas and it would not refire. After adding the gas it ran rough and not above an idle. Then it wouldn't even fire. The engine has 300 hours on it. It's in Florida and is dry stored and used weekly. Anone have any thoughts on what might be going on?
