My engine yamaha 115 idles roughly so I took a fuel sample to make sur it wasnt water in the tank and there is no water but there is a waterlike substance FLOATING on the gasoline.... heres a picture: any clues as to what it could be so I can fix my problem?

Let that jar sit for 2 more days and post a picture then.----New boat / new motor ?-----Have the dealer clean out the entire fuel system.-----Did they do the pre delivery check ?

Letting it sit will say nothing more the maybe how much worst the fuel is, its bad and needs go go
What is the history of the boat and motor?
