River decision with set

[gapeno]

SB is 54/15/1.39 over 418 hands, and the usual loose fish.
CO is 27/20/2.46 over 202 hands, and calls down too much (48%).

I have had a rush at the table, playing 48% of my hands, and winning over 60BB in 35 minutes, a lot of that from CO.

Number of players : 5

Am I too passive on turn?
Is folding the correct thing to do on river?
Anything else?
