I need a part # for a IAC that is used on a 525 EFI with a Whipple. This IAC has an external flame arrester and mounts to a manifold with a hose to the blower. I have those IAC's on my boat but I can't find a part # so that I can replace them. Does anyone have that part number?

Thanks

Your Mercruiser engine serial number is always the best way to help find correct parts, But item number 15 in the following link looks to be the Blue Idle Air Valve Assembly you are asking for, http://www.mercruiserparts.com/bam/s...1345/10127/110

Thank you, my motors a custome built 572's with 4L Whipples so no serial number to use. They have the Mercuiser 555 ECU's so I know the 525 IAC will work. Either way thank you for your help!

I have a NAPA # at the shop. Call me tomorrow and I can get it for you. 615-216-7449

Eddie thanks I would like to get that # from you. Also will you inbox me your email address I have a few more questions I want to ask you about the problems we talked about on the phone. I just I don't want to call while your trying to get some work done. I'll just email you and you can get back to me after business hours when you have more time. I tried to send it on OSO but you inbox is full.
Thanks
