We've 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 makeing installation neat and easy. Three rotary dials and an LED display simplfy 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.
