The Thunderbolt ignition is really a great marine ignition system. All you have to do is replace the distributor pick up's and caps every 2-3 years. We raced with the standard Thunderbolt IV for 10+ years and never had a any issues. They should perform flawlessly to minimum of 6000 RPM.
IMO, the MSD system is a step backward in performance and reliability.
