From early morning launches to long pulls across open water, your boat’s performance depends on clean, consistent ignition power. Smooth idle while maneuvering through the marina and instant throttle response when you open it up can make every outing more enjoyable and more controlled. Designed to thrive in harsh marine environments while delivering precise tuning at your fingertips, the ignition upgrade serious boaters rely on is the MSD Digital 6M-3L Marine Ignition Control.

The MSD Digital 6M-3L Marine Ignition Control is a UL listed, fully sealed capacitive discharge ignition module built specifically for marine use, featuring a single sealed connector that keeps wiring organized and installation straightforward. Three rotary dials paired with a bright LED display allow quick adjustment of cylinder select, start retard, and rev limiter settings without plug in chips, while the display can show live tach readings on V8 engines, battery voltage, selected rev limit, highest RPM recorded over the last 20 minutes, and more. The system delivers multiple sparks from idle to 3,000 RPM for improved idle quality and throttle response, then continues with strong capacitive discharge sparks through 12,000 RPM, producing up to 535 volts with a Blaster Coil or 550 volts with HVC Coil PN 8250 and up to 150 mJ of spark energy. Additional highlights include adjustable start retard in 0, 10, or 20 degree increments, a smooth rev limiter to help protect engine components, shift interrupt capability for easier gear changes, reverse polarity and overheat protection, compatibility with magnetic pickup, amplifier, and points inputs, low 0.8 amp per 1,000 RPM current draw, dependable starting down to 6 volts, and support for 4, 6, and 8 cylinder engines. This part is legal for sale and use on uncontrolled, non emissions controlled vehicles.
