Review on Mercruiser Thunderbolt Ignition Mercury Marine by Jamal Gerrero

Revainrating 3 out of 5

Non-OEM, should have bought the real deal

Not sure yet. The box coil was in an oil stain on the tailgate. Opened it up and smelled oil. There were no drips, but I won't know how good or bad it is until I install tomorrow. I will probably buy a True Mercruiser reel in the near future.

Pros
  • Only works with HEI systems, will not work with point ignition systems
Cons
  • Crumpled packaging
