A marginal hand

[Praxx]

Very loose table, people are calling with anything.

Final Pot: 6.75 BB

With three callers, I figure the BB bet and UTG call, either one of them has at least a two or five. Im also drawing to two outs for a full house. It seems like a marginal call to me, probably 30% chance that I am ahead.

I'm thinking that I should raise this flop but I'm not sure. Any advice?
