If you're looking for a simple, powerful solution for high performance boating, then look no further. The Marine DUI (Davis Unified Ignition) is a one-piece distributor that is virtually waterproof and will withstand the severe vibrations of a marine engine. These electronic high-voltage coils are built inside of the distributors and produce a longer spark duration, allowing you to widen your plug gap up to .055’’ and get a more complete fuel burn. Marine D.U.I. distributors we sell available in performance versions that crank up to 7,000 rpm. They are calibrated by machine to dial-in the smoothest advance curve for your application. A special weight and spring assembly is hand fitted and dialed-in using a distributor machine for a precise timing curve that will match the specifications of your engine and boat. They are hand-assembled, polished, lubed, and checked for exact tolerances.
Increase performance and simplify the ignition system in your boat by installing our Marine DUI Distributor!
