Related to this valve is that there is a whistling from our 50 hp starting at about 2200 rpm. Finally figured out the whistling is coming from the IAC. From the open, upper port sucking in air. Weird but the service manager says that's fine as long as idle is okay. Thanks for your video
The other port is open to the atmosphere to compensate for air density. therefore if operating on a fresh water lake above sea level it will take this into account..
I have a 2007 mercury 25 hp 4 stroke that when the high idle lever is up it will run. As soon as I try to lower the lever to put it in reverse, the motor will die. Any suggestions would be highly appreciated. Short boating season here in east, central Illinois.
Since you cut off all that hair, looks a little you aged some. But keep up those awesome videos, haven’t seen seen one in awhile of you fishing. Do you still have the Maverick and have you done any driving from the tuna tower?
Yea man, kids will age you quick. Haha No I sold the maverick a while back. I’ve been fishing a few times just been slacking on putting a video together.
I had the same problem with my 2004 40EFI4ST. I refitted the loose hose and problem solved. Thanks for your video. Garry @ Forster NSW.
Glad I could help. Thanks for commenting.
We had this exact problem, thank you for pointing out the tube, ours had come off. All fixed! Thank you!
So glad this helped!
Thanks for this video made my day much easier. My hose had disconnected to!
Glad it helped!
This is the video that saved me a couple bucks and got us back on the water! Thank you!
Glad we could help! 👍

thank you for this video! This saved me a ton of time and probably money too!
You literally just saved me on the water!! Thank you
Glad we could help! 🤠
Would that valve cause mt merc 50 4 stroke to start and idle then die when throttling up?
@lostviking540 id bet you have a fuel pump going out.
At 0:10 you can see the hose was disconnected. You should have tried the old one with the hose reconnected.
One hose plug stays off one stays on it was def the sensor bad. Thanks for the comment though.
I have the same issue (high idle) with a F225 Yamaha, wondering if the fix is similar
Yes should be something similar
