Davis Unified Ignition D.U.I. Marine Distributors

Waterproof Performance Distributors

Better throttle response, smooth advance curve and maximum conductivity are just a few advantages you can expect with a Davis Unified Ignition (D.U.I.) Marine Distributor. These one-piece waterproof models will increase your boat's performance with a single 12-volt hot wire hook-up. Precision-built DUI marine distributors are available in two models with exact off-the-shelf tolerances: a 7000 version for stock to lightly-modified (up to 7000 rpm) engines, and the 10000 version for racing and high-performance (up to 10,000 rpm) engines.
