Replaced OEM in a Mercury 40hp
It was a simple item to replace and it brought spark back to my engine. I'm not sure about longevity but it worked as soon as I installed it this afternoon. I'll post a follow-up if it goes bad in the near future.

Worked on my 1995 Mercury 115
The media could not be loaded. NOTE: Per the CDI web site, they will not provide free technical support to DIY buyers. They do provide paid support to those customers. Also, warranty is provided only through marine repair shops and not DIY-ers.My 1995 Mercury 115 was not starting after it warmed up and you shut it off. Then it just wouldn't start at all. I checked all the fuel lines and replaced the gaskets in the fuel pump; no difference. I knew the compression was good so the only thing left was spark. Using my shop manual I did some resistance tests but they weren't any help at all so I took a stab in the dark and bought a CDI stator along with this CDI switch box (power pack). Mercury recommends replacing both at the same time because if one fails it can damage the other. I installed the CDI stator according to the instructions included but there weren't any for the switch box. So I just swapped wires, one post at a time. Now I'm back in business.

Perfect match
Works flawlessly, boat was only running on 2 cylinders swapped this and now it runs smooth on all 4. Had all the correct labeling for the wiring and everything. Seems to be as of the same quality as the OEM
