## Customer Reviews

### ⭐⭐⭐⭐⭐ IAC
*by J***E on July 10, 2024*

Fit perfect

### ⭐⭐⭐⭐⭐ Works on mine
*by B***T on August 20, 2020*

Fit my 1999 5.0L EFI Mercruiser engine. Cured MOST stalls. I’m not totally sure this was the culprit of my docking stalls but that said, It fit perfect. There is a noticeable difference in my stalls though, much less at idle speed. 5 stars for me..

### ⭐ did not fit
*by D***B on July 11, 2019*

did not fit bolt pattern and the wiring was too short to reach it at that angle. so not happy
