Review on 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) by Zachary Greene

Works perfectly. - Motorcycle & Powersports

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.

Pros
  • Decent Performance
Cons
  • Quality
