The MSD 6M-2L Ignition Control is designed for performance marine applications where a high energy and reliable ignition is a necessity. The capacitive discharge (CD) design of the MSD produces full power sparks throughout your boat’s entire rpm range. Below 3,000 rpm, a series of multiple sparks burn in the cylinder for 20° of crankshaft rotation ensuring complete combustion. Together, these sparks produce easier starting, great throttle response, more power and reduced plug fouling during idling. Weathertight connectors securely lock together to provide reliable connections that are unaffected by water, oil, gasoline and most other chemicals associated with boats. The 6M-2L’s electrical circuitry from marine conditions, the entire unit is potted with a polyurethane compound. This material prevents the electrical components from coming into contact with water or other chemicals. The 6M-2L also features a built-in Soft Touch Rev Control that will save your engine from overrev damage. The rpm limit is set with sealed rpm modules (see below). The 6M-2L can be triggered by either a magnetic pickup (distributor or crank trigger), amplifier or by a breaker point distributor. The cable harness has the proper connector so you can plug the 6M-2L into one of the Pro-Billet MSD Marine distributors.
