Item Details

  • MerCruiser Thunderbolt IV Breakerless Electronic Timing High Energy Ignition Amplifier Module
    • V824 Stamp-(Not always visible) I can't see it on this one, but the DIFFERENT V822 stamped ones, the "V822" is hard to miss (right next to the sticker) if it has it so make sure to not mix these up
  • Good Condition
    • Please Note..... The really the only thing that can happen with these is that THEY ARE WORKING OR THEY ARE NOT. The primary symptom of a bad ignition amplifier is NO SPARK AT ALL. Always make sure you connections are clean & tight while troubleshooting your existing one.
  • Generally Found Mercruiser V8 Models (305 5.0L & 350 5.7L) 1981-1987
    •  If you are unsure if this is right for you, please ask
  • Part number:
    • 390-7804A 3 15248T02
    • V8-24 Stamp (some of the 305 Models will have a V822 Stamp on the amplifier box which is technically a different box with 22 degree timing advance curve)
  • Purchase with confidence!
