<h3>About CDI Electronics</h3><p>Since its founding in 1982, <strong>CDI Electronics</strong> has grown from a small outboard repair shop into one of the most trusted names in marine ignition and electrical components. The company originally operated under the name Rapair Incorporated, spending years repairing outboard engine ignition systems and accumulating deep, hands-on knowledge of exactly how and why marine electrical systems fail. That hard-won expertise laid the groundwork for a pivotal shift in 1995, when CDI began designing and manufacturing its own line of replacement components — a move that gave birth to the CDI Electronics brand the marine industry relies on today.</p><p>Headquartered in Huntsville, Alabama, CDI Electronics designs and builds its products domestically, maintaining tight control over engineering and quality standards. The result is a catalog of components that offer a compelling alternative to expensive OEM parts without compromising on durability or performance — a critical consideration in the demanding marine environment, where corrosion, moisture, vibration, and extreme temperatures can take a relentless toll on electrical systems.</p><h3>A Complete Marine Ignition Solution</h3><p>CDI Electronics' product lineup spans the full spectrum of marine ignition and charging needs. Their extensive range of <a href="/7290-cdi-electronics-ignition-repair-parts-200570">ignition repair parts</a> includes ignition coils, switch boxes, triggers, rectifiers, voltage regulators, and wiring harnesses — essentially every component that keeps an outboard's spark and charging system firing correctly. Whether a technician is rebuilding a Johnson/Evinrude, Mercury/Mariner, or Yamaha powerhead, CDI's catalog is engineered to cover a remarkably wide range of makes, models, and model years.</p><p>On the charging side, CDI offers a strong selection of <a href="/7290-cdi-electronics-alternator-stator-10030">alternator stators</a> that are engineered to match OEM output specifications while standing up to the unique stresses of the marine environment. Stators are the heart of an outboard's charging and ignition power generation system, and CDI's focus on precision winding and materials means boaters and technicians can install with confidence. CDI also carries high-output XT-Series alternators designed specifically for performance inboard and wake boat applications where electrical demand at idle is especially high.</p><p>For engines that rely on capacitor discharge ignition architecture, CDI's lineup of <a href="/7290-cdi-electronics-ignition-power-pack-15557">ignition power packs</a> — including power packs and switch boxes — provide the critical energy storage and delivery that drives the ignition coils. These components are engineered to deliver consistent, reliable spark timing across the full RPM range, and CDI offers both standard-replacement and high-performance variants for a wide range of outboard applications.</p><h3>The M.E.D.S. Diagnostic Advantage</h3><p>Beyond replacement parts, CDI Electronics has developed the <strong>Marine Engine Diagnostic System (M.E.D.S.)</strong>, an advanced software-based diagnostic platform designed specifically for troubleshooting marine engines. M.E.D.S. works across most major outboard brands, giving marine technicians a unified tool for reading live engine data, pinpointing ignition faults, and reducing diagnostic guesswork — a significant advantage in a repair environment where misdiagnosis can be costly.</p><h3>Why Choose CDI Electronics?</h3><ul style="list-style:disc"><li>Over 40 years of focused marine ignition expertise dating back to 1982</li><li>Designed and manufactured in Huntsville, Alabama</li><li>Cost-effective OEM-quality alternatives backed by engineering know-how</li><li>Comprehensive coverage for major outboard brands including Mercury, Johnson, Evinrude, and Yamaha</li><li>Full-spectrum catalog: from individual coils and triggers to complete ignition kits and diagnostic systems</li></ul>
