CDI Electronics Distributor Caps & Tune Up Kits: Marine Ignition Expertise You Can Trust

When it comes to marine ignition maintenance, few names carry as much weight as CDI Electronics. What sets CDI apart in the Distributor Caps & Tune Up Kits category isn't just the quality of the parts themselves — it's the deep engineering knowledge baked into every component. CDI was founded in 1982 as "Rapair Incorporated," initially engaged in providing repair services for outboard ignitions, working out of a rented garage in Madison, Alabama. Rapair had learned nearly everything that could go wrong with an electronic ignition, and they incorporated that knowledge into their improved designs.

In 1995, the company began to design, develop, and manufacture their own line of replacement ignition components under the brand name CDI Electronics. Rapair had learned nearly everything that could go wrong with an electronic ignition, and they incorporated that knowledge into their improved designs — as a result, CDI Ignitions quickly earned a reputation as a reliable, cost-effective alternative to OEM-supplied components.

Distributor Caps & Tune Up Kits Built for the Marine Environment

These components are engineered to address the harsh marine environment where corrosion, vibration, and moisture can compromise electrical performance. A distributor cap is the gateway for high-voltage spark distribution to each cylinder — when it cracks, corrodes, or arcs internally, the entire engine suffers. CDI's marine-grade caps and tune up assemblies are designed from the ground up to resist the punishing conditions that salt air, humidity, and constant vibration create on the water.

CDI's catalog organizes its ignition tune-up products under dedicated categories including Condensers, Contact Sets, and Tune Up Kits (E66) as well as Distributor Caps (E64) and Rotors (E65) — a structured lineup that makes it straightforward for technicians and DIY boaters alike to identify the correct component for their engine. CDI Electronics' distributor cap lineup includes applications such as a Mercury 6-cylinder distributor cap , and their part numbers are widely recognized as cross-references to OEM Mercury, MerCruiser, OMC/BRP, Crusader, Indmar, and Volvo components.

For example, CDI's E64-series caps cover applications like MerCruiser V8 GM & MIE engine Delco ignition systems, replacing OEM numbers across multiple major manufacturers including OMC/BRP, Crusader, GLM, Indmar, Mercury, and Volvo. This broad cross-reference compatibility is a hallmark of the CDI approach: one well-engineered part that replaces a long list of OEM SKUs, reducing confusion and cost.
