This is what they show. It is either MerCruiser part number 803149 or 805224A1. It's a great website for finding parts.

You bet! Anything to help my fellow boaters save a few bucks.

Thanks gonna grab a spare

Lots of marine parts available at auto parts stores for far less money. The marina guys will of course tell you you can't use the parts. Napa has merc numbers on many parts now.

Had one go out 4 years ago and no spare then. Thanks for reminding me. Order done!

I just ordered one for the onboard tool bag. Thanks for the post.

Glad to read you guys are getting spares onboard. When my SC5000 started beeping I checked the active alarm and it said 'port IAC fault'. It sure was nice to have one on hand and fix it on the spot.

And quick shipping! Received my spare IAC yesterday $49 to the door. Thanks again for the info.

Thanks for posting , I am going to buy a couple IAC and a few other sensors that I can see on there site TPS , CRANK sensors
I punched in the correct motor type (mercruiser 496Ho 2001 but when I click on fuel pump , the pump that comes up on screen don't look anything like the pump on my motor , I am talking about the Boost pump . As I read on here best to carry a spare , am i missing something here . This is on the Rock auto .com site .?? Thanks

It's a Delphi CV10103 made for a 2002 Ford Windstar. I bought just it Amazon Prime for $47.

OOPS sorry that's a different IAC. the one above is for the 5.7 / 6.2 liter
