    Wow,

    Thanks for this thread. I just got done shopping for Mercury P/N 332 -7778 switch boxes (CDI 114-7778 Ignition packs). Things got complicated.

    The very inexpensive "Oriental Power" boxes appear to be marketed as CDI brand boxes but the fine print says that they can "replace the CDI stuff". What a snake pit.

    Is Pro Marine selling the real Sierras Merc boxes now filled with that clear potting goo? That clear potting goo is new to me?

    I was looking at getting the CDI 114 7778 boxes with the ground wire still shown black potting goo, with the built in bias protection. I'll have to call CDI to find out whats going on. It's hard to tell who is selling what.

    Thanks to all for asking and posting this info!

    "CDI" is the type of ignition system so the ads for the knockoffs arent necessarily wrong. What throws most people off is the fact that "CDI" is in "CDI Electronics" brand name so they assume "CDI" is the brand. You can buy the genuine Sierra boxes on amazon also. Just make sure the description says made in Germany by Sierra international. Pro marine USA does sell them but they seem to be out of stock more often than they have them available.

    Over the years I’ve had great luck with either OEM or CDI from Pro Marine but I always buy them in pairs of like parts and change both at same time …

    Gentlemen,

    Thanks for all the info it helps.

    My recent inquires told me the Pro Marine 18-5775 with the clear potting material and the two white do dads encased at the top of the PCB are the German Sierra Packs.

    The less expensive ones with the Red/Orange do dads are made by others.

    The two do dads I mentioned above, appear to be "Mica" style capacitors. However I have yet to confirm what that actual component type is.
