Review on 🚢 Mercury Muffler-IAC for Mercruiser by Alejandro Labustin

When I first heard the hiss I thought it was a major vacuum leak, which technically it was. I found YouTube where a guy explained what's going on. I couldn't believe how loud the suction sound was and that it was coming from the idle control valve. I'm not sure where the muffler/filter went, but I think I'll talk to the IAC control valve to see if it's stuck in there. The bottom line is that the second I put the little muffler on, the audio went back to normal. The part I received was sealed and had two silencers inside. High marks in all aspects of purchase and delivery.
