Description
Technical Specs
MSD has raised the bar and added an all-new UL listed marine ignition box to our lineup. The 6M-3L is a fully sealed unit with a single wiring connector making installation neat and easy.
Three rotary dials and an LED display simplify setting the cylinder select, start retard and rev limiter. Plug-in rev limiter chips and hard to read dials are a thing of the past. For diagnostic purposes, the LED display can also be set to a live tach mode on V8's and even display battery voltage with the turn of a knob.
The 6M-3L is a capacitive discharge ignition that multi-sparks from idle to 3,000 RPM providing a clean idle and quick throttle response. Above 3,000, capacitive discharge sparks will run clean through 12,000 RPM . Boasting more features and higher spark energy than its predecessor, the 6M-3L is the performance upgrade your boat needs!

Large, easy to read LED display
Shift interrupt feature eases shifting
