MSD 6560 6M-2L Marine Certified Ignition Control with Rev Limiter

The MSD 6560 6M-2L Marine Certified Ignition Control is a high-performance capacitive discharge (CD) ignition system engineered specifically for demanding marine applications. Building on the proven 6M-2 platform, the 6M-2L adds a built-in Soft-Touch Rev Limiter to protect your engine from costly overrev damage. The rev limit is set using MSD's sealed marine RPM modules, allowing precise, application-specific tuning.

The CD ignition design delivers full-power sparks across the entire RPM range. Below 3,000 RPM, multiple sparks fire in the cylinder for 20° of crankshaft rotation to ensure complete combustion, resulting in easier cold starts, crisper throttle response, stronger idle quality, and reduced spark plug fouling.

Key Features:

• UL Approved for Marine Use — certified for safe operation in marine engine compartments
• Built-In Soft-Touch Rev Limiter — RPM limit set via sealed marine RPM modules (sold separately)
• Capacitive Discharge (CD) Design — delivers full-power, multiple sparks throughout the entire RPM range
• Polyurethane-Potted Circuitry — entire unit encapsulated to prevent water and chemical ingress
• Weathertight Connectors — multi-ribbed sealed connectors resist water, oil, gasoline, and other marine chemicals
• Current Draw: 1 Amp per 1,000 RPM
• Maximum RPM: 15,000 RPM at 14.4 volts
• Operating Voltage: 12–18 volts, negative ground
• Primary Voltage: 460–480V
• Secondary Voltage: 45,000V
• Spark Energy: 105–115 mJ per spark
• Spark Duration: 20° of crankshaft rotation
• Trigger Compatibility: Magnetic pickup (distributor or crank trigger), amplifier, or breaker point distributor
• Direct plug-in compatibility with MSD Pro-Billet Marine distributors via included cable harness
• Same mounting footprint as the original 6M-2 — fits existing brackets without modification
• Tach output terminal for tachometers, shift lights, and other RPM-activated accessories

The MSD 6560 is the go-to ignition control for performance marine builds where reliability, ignition energy, and engine protection are non-negotiable. Its weatherproof construction and UL marine certification make it suitable for inboard and stern-drive marine applications.
