Fold. You are not getting close to the odds you need to make this call, and if you miss your draw you are done.

This may or may not be right. There is 600 in the pot and your call is 300. The pot is offering you 2 to 1 on your call. With this flush draw under the best case scenario, you have 9 outs or odds of 1.9 to 1, so the odds are there. The problem here is the limpers, if at least one of them has a flush draw, then you are down to 7 outs, and you would need odds of 2.6 to 1 to call.

If you let it go, you are short stacked but have several rounds around the table left. If you push, 65% if the time you are done, and 35% of the time you double or triple. Mi_T_Sharp is right about not having the odds to push, which is the only play you have with your stack.

It's up to you, gamble or try to hold out for a pre-flop push. I don't see a clear right or wrong. The advatage of the gamble, I see your push getting called and you possibly doubling (or tripling ) up. Then you are in a strong position for the SNG's remainder, or you are out and can go spend time at another one. If you fold, then you remain in a precarious but not yet desperate situation. It is up you, as either play seems feasible.
