I have a 2003 Mercury 225 EFI saltwater series that has a hard time starting when hot, happens after we troll all day and then pull up to the fish cleaning dock. When I start up to leave the motor will be hard to start, if it does start it will sputter and die. The only way to keep it running is to rev the engine up for a little while. I have replaced fuel filters, fuel lines, spark plugs. The engine runs great when cold and hot. It will run all day no problems, it all happens on a hot restart.
