FuelTech’s SparkPRO-3 Nautical / Off-Road model is a high-energy inductive ignition module designed to be used with ignition coils without an igniter (dumb coils) specifically in marine and offroad applications. The SparkPRO-3 (Nautical / Off-Road) had a redesigned case, specifically designed to keep water and fine dust particles from damaging the ignition module. The module has 3 ignition outputs, each output may be connected to only one coil at a time, and is available in versions from 1 to 8 ignition outputs. It has a high voltage of up to 430V at the coil’s primary. SparkPRO ignition modules are compatible with any programmable ECU that has dwell control but cannot be used with a stock ECU.
