The MSD 6M-2L Ignition Control is built for performance marine applications that demand a high-energy, reliable spark. Its capacitive discharge design delivers full-power sparks throughout the engine's RPM range, and below 3,000 RPM a series of multiple sparks burns for 20 degrees of crankshaft rotation for cleaner combustion, easier starting, better throttle response, and reduced plug fouling at idle. Weathertight connectors and a fully potted polyurethane housing protect the electronics from water, oil, gasoline, and other marine chemicals, and a built-in Soft Touch Rev Control protects the engine from overrev damage.
