Our one-piece ignition systems for Marine applications are virtually waterproof. The electronic Dyna-Module and the 50,000 volt coil are built inside the distributor, protecting them from moisture and the severe vibrations that marine engines must withstand. The Marine DUI is an easy drop-in unit that requires only one hot wire for hookup. Other performance ignitions require an array of messy wiring which is always suspect to the hazards of boating.

We recommend you run a wider plug gap with our ignitions. Our coils and modules produce a much hotter spark providing a more powerful burn of the fuel mixture by opening up the plug gap to .055".

Every distributor is calibrated on a distributor machine that will give you the instant throttle response that other off-the-shelf distributors will not provide. A very smooth advance curve is dialed in, whether it be for performance cruising or all out racing.

Our marine distributors are blueprinted. Each one is polished, lubed and checked for exact tolerances as they are assembled. Flame arrestors are installed on each housing.

Two versions are available for both the GM Marine DUI and the Ford Marine DUI. The Performance version is designed for 7000 rpms and the Racing version is built for 9000 rpms.
