Time to fold a flush draw?

[Ampelmann]

Only a couple of hands, but all villains seem a bit laggy.

Even if noone has a boat yet I'm not drawing to 9 outs here. 7 outs would just be enough to see the river, but (1) I may be drawing dead (2) the turn may get 3-bet and capped, giving me bad odds. I don't think I can rely too much on implied odds.

Fold?
