Worked great
Got a IAC output low warning on my 496HO inboard while underway. Once back to the dock, found the old one actually melting and stuck closed. Replaced both engine Idle Air Control valves with these. Alarm went away and engines idle beautifully at 700 rpm. Took 15 minutes to change both.

Mercruiser 5.0 MPI
If you have a Mercruiser 5.0 MPI or similar engine you should keep a spare IAC on hand. These IAC valves can fail quickly and leave you stranded. It takes about 2 minutes to change one with and allen wrench. Happened to me twice.

Dont work correctly
I purchased two of these. Neither one worked correctly. One had the idle too high, 850 instead of 650, and the other one had the idle rev up and down from 250rpm to 500 rpm. Sent them both back.
