The Buckshot Racing #77 Spark Tester is specifically engineered for high-performance and racing outboard ignition systems, supporting 2-cylinder, 3-cylinder, 4-cylinder, 6-cylinder, and 8-cylinder powerheads.
It is fully compatible with both 2-stroke and 4-stroke outboards, including the Mercury Racing 300R, 400R, and the latest 500R, as well as high-output setups like the Monty V8 with its advanced ignition configuration.
Designed for precise ignition diagnostics, this tester ensures accurate voltage measurements critical for peak engine performance in marine racing applications.
Built with the CDI Electronics insulated body, the Buckshot Racing #77 Spark Tester provides adjustable spark gap measurement with 1/8-inch incremental adjustment points, allowing users to record actual kilovolt (kV) output per cylinder.
This feature is critical for diagnosing ignition performance across different engine setups, as each incremental spark gap corresponds to a specific voltage output requirement.
At 1/8-inch, a properly functioning ignition system should deliver approximately 5,000 volts, while at 1/4-inch, it should produce 10,000 volts. As the gap increases, so does the required ignition voltage, reaching 20,000 volts at 3/8-inch, 30,000 volts at 1/2-inch, and up to 40,000 volts at 5/8-inch.
The Buckshot Racing #77 Spark Tester accommodates an extended gap range, allowing measurements for ignition system intended for high-performance racing applications. This capability is crucial for verifying whether systems such as the Mercury V6 2-Stroke outboard are producing the full 30,000+ volts per cylinder required for peak combustion efficiency.
To safeguard ignition components from damage, the unit features a flexible, marine-grade 8AWG ground strap with a secure grounding clip. Its shock-resistant, fully insulated casing protects against accidental electrical discharge, while fire-resistant materials mitigate the risks associated with rogue sparks.
Additional rubber boot insulators encase each probe, offering enhanced protection for both the user and sensitive marine electronics.
As an improved CDI electronics tester (Part Number: 511-9766), this tool is indispensable for diagnosing capacitor discharge ignition (CDI) systems, ensuring proper ignition coil performance, spark plug efficiency, and overall electrical integrity in racing and high-output marine engines.
Proudly assembled in the USA, the Buckshot Racing #77 Spark Tester is the definitive tool for professional ignition diagnostics in high-performance marine applications. Designed for reliability, accuracy, and durability, it is an essential component for anyone maintaining or tuning racing outboard engines where ignition system precision is critical.
