High-performance CDI Switch Box Power Pack for Mercury Outboard 4 Cylinder Engines (40-125 HP) - Model 332-5772 A3-A7 332-5772A5, 332-5772A7 (J750) Review

. This was exactly what was advertised and I received it very quickly. I can say after installing it on the boat it worked perfectly, I'm very satisfied

PSU installed and not good as it didn't work properly. I personally tested it and it didn't work, took it to a marine mechanic and confirmed the CDI was not working properly.

Boat shut down on water, no spark in any cylinder. The stator and flip-flop tested OK. Replaced it with a Mercury 86 and it started again. Good deal compared to the original part, hope it lasts a while.

This was the final step in getting the old engine running again. Nothing to say except that it works. Replaced the original on a 50hp 2-stroke 4-cylinder Mercury engine. 1980

I had a problem with cylinders 3 and 4 not working. After some research I checked the coils, stator and trigger. Everything seemed to work when I typed it in, but nothing was posted. I am pleased to report that all four are now firing. I've regained over 50% of my strength. It worked and fitted perfectly. The only reason I noticed this was because the one you have is different than the one in the photo.

Installed on the early 1990's Mercury Force 120 to solve the problem of no spark at all four spark plugs. It fixed the issue and worked reliably in Fall 2020 and Spring/Summer 2021. Still working. Was skeptical because it's part of the OEM cost. Build quality may be slightly worse than OEM. The bolts and nuts that attach the ignition wires are steel, not brass. It doesn't seem to be a problem.
