Hi, I have a '96 Malibu with a Mercruiser 350 Magnum Tournament Ski (carbuerated) engine. How can I tell whether I have a Thunderbolt IV or a Thunderbolt V ignition? If it helps, my engine serial number is 0F819569. Thanks!

Thanks for the reply.....There are two wires coming out of the distributor (from the ignition sensor) with bullet connectors. Also, there are two large connectors on the backside of the distributor. Where is the ignition box?
