Top pair and nut flush draw

1/2 NL, effective stacks about 400 with main villain. 5 limpers including SB, I raise to 15 in BB with AsJs and get 3 callers (sometimes this sizing gets one or no callers). Flop is Jc7s4s (about 55), I lead for 25 (could go for a checkraise or bet bigger), UTG calls, others fold. Turn is Td for Jc7s4sTd (about 105), I check (could bet) UTG bets 45, I call. River is 5h for Jc7s4sTd5h (about 195), I check, UTG bets 50, I call.
