Ahoy! If you're looking for a simple, powerful solution for high performance boating, then these Davis Unified Ignition marine D.U.I. distributors from Performance

Ahoy! If you're looking for a simple, powerful solution for high performance boating, then these Davis Unified Ignition marine D.U.I. distributors from Performance Distributors are the answer. These virtually waterproof and vibration-proof distributors are easy drop-in units with one-wire hookup. There are no wiring hazards to leave you adrift and no hassles! The electronic Dyna-Module and high-voltage coil are built inside of the distributors and produce a longer spark duration, allowing you to widen your plug gap and get a more complete fuel burn. Marine D.U.I. distributors are available in performance versions that crank up to 7,000 rpm and racing versions at 10,000 rpm. D.U.I. distributors are calibrated by machine to dial-in the smoothest advance curve for your application. They are hand-assembled, polished, lubed, and checked for exact tolerances, and the housings are drilled with flame arrestor holes. All of these features allow you to navigate with instant throttle response and more power. Whether you're taking a leisurely ride around the lakes, offshore cruising, or running the waves, anchor your boat with high performance marine D.U.I. distributors from Performance Distributors.
