Check the water separator for water.

Don't start dumping a bunch of different remedies in a can in it till you find the problem.
If it's water, contact the marina. They will have to foot the bill to get things fixed.
Like mentioned, check the filter for water.
Just remove it, dump the contents in a clear container and see if the water seperates and sits on the bottom. Note, It could be ALL water and hard to tell. But find out soon, the fuel injection system does not like to sit in water for very long.
