1 Used exhaust elbow (865951A01) 2 Exhaust shutters (807166A1) with 3 rubber grommets In good condition, came off my twin 2011 350 Mag Mercruiser V8's. I decided since one side was fried that I would replace all. These are the two that I took off which turned out to be in good condition. $150 for all or $70 each for shutters and $50 for elbow. Shutters are $168 each new and elbows are $90 to $420 each new.
