Is this flush draw too fishy of a play?

[SonOfWestwood]

Are the pre-flop & flop calls too fishy? Had lots of limpers ahead of me, so I figured it's an okay limp from the SB. I definitely felt he'd be along for the ride if I hit the flush for the implied odds.

MP1 is 40/14/2 after 43 hands and hasn't been too impressive so far, the latest thing I saw being him going all in pre-flop w/ AK after being limp re-raised. The flop raise makes me think he's got Kx, possibly KQ (but I suspect he'd PFR with this).
