Sklansky has shown that you can count runner runner draws as approximately one out if seeing both cards. So, if there were "lots of limpers" let's say four, at 150bb, you raise to 600 and get one caller the pot is around 1875 with the blinds. If you moved in for any amount around that the call isn't that bad: 4 outs to the gutshot, one runner runner flush out, plus three outs to his overcard (he doesn't know you have aces, so counting these is pretty legit) = 8 outs, or just about 2:1 to win. Not such a "donkey" now is he?
Please post a real hand history next time (if you want actually discussion), or put this in the Bad Beats forum if you just want to whine.
