Buckshot Racing #77 now offers a complete ignition upgrade kit combining CDI ignition coils with custom-built MSD high-performance spark plug wires, engineered specifically for Mercury 2.0L, 2.4L, and 2.5L two-stroke V6 outboard engines produced from 1976 through 1999.
This package is designed for boat owners who want to restore or improve ignition performance with components built for the demands of marine engines.
Our coils are sourced at the distributor level to maintain competitive pricing, while the plug wires are custom assembled using MSD high-performance materials. Together, they deliver reliable spark energy, cleaner combustion, and consistent ignition performance for both fishing and performance outboards.
Each CDI ignition coil includes the ferrite core properly installed and siliconed in place, helping stabilize the ignition signal and reduce electrical noise that can interfere with ignition timing or ECU operation.
Designed for Mercury V6 Two-Stroke Engines
This ignition setup is compatible with a wide range of Mercury Marine, Mercury Racing, and Mariner V6 outboards, including engines rated from 135 HP through 245 HP, along with performance models such as the 260 ROS and 300 Drag. These engines use legacy ignition coil systems that benefit from improved spark delivery and modern wire technology.
The system is designed for Mercury 2.0-liter, 2.4-liter, and 2.5-liter V6 two-stroke engines, commonly found in XR2, XR4, XR6, Black Max, and other high-performance Mercury outboards built between the mid-1970s and late 1990s.
Custom MSD High-Performance Spark Plug Wires
To maximize ignition efficiency, each coil set is paired with custom-built MSD high-performance spark plug wires. These wires are built specifically for legacy Mercury coil systems and feature MSD 8mm spiral-wound suppression core technology.
The spiral-wound conductor provides very low electrical resistance—approximately 250 ohms per wire—while suppressing EMI and RFI interference. This design helps deliver stronger spark energy to the plugs while reducing ignition noise that can affect other onboard electronics.
The result is cleaner combustion, stronger ignition spark, and improved throttle response, particularly on engines operating under heavy load or high RPM conditions.
Marine-Grade Silicone Construction
Every wire is protected by a 100% pure silicone outer jacket, designed to withstand the extreme conditions found in marine environments. The silicone insulation resists heat, fuel exposure, oil contamination, UV radiation, and constant vibration, preventing cracking or degradation common with lower-quality rubber plug wires.
Each plug wire measures 6 inches in length and is terminated with MSD-style 180-degree bell boots, molded from high-temperature silicone. These boots are designed to fit the larger socket-style terminals used on legacy Mercury ignition coils, providing a tight, vibration-resistant connection.
Professional-Grade Terminals and Connections
The plug wires utilize MSD dual-crimp terminals, the same design used in professional racing ignition systems. These terminals feature two separate crimp zones—one securing the conductor sleeve and the other gripping the conductor core—to ensure a solid electrical connection.
A stainless steel “Click-Lock” retention tab locks the terminal securely into the ignition coil socket, preventing loosening under vibration. This design eliminates the need to bend the wire sharply around the coil, reducing internal stress and improving long-term reliability.
Complete Ignition Set Ready for Installation
Each package includes a complete set of six CDI ignition coils paired with six custom MSD spark plug wires, fully assembled with boots and terminals installed. The set is ready for plug-and-play installation on Mercury V6 two-stroke engines.
A small tube of Super Lube dielectric grease is included to protect electrical connections, prevent corrosion, and ensure proper sealing of the terminals.
Built for Performance and Reliability
For owners restoring classic Mercury V6 two-stroke outboards or upgrading ignition systems on performance engines, this combination of CDI ignition coils and MSD high-performance spark plug wires delivers a dependable spark under demanding marine conditions.
Whether installed on a Mercury 2.0L, 2.4L, or 2.5L V6 fishing engine, bass boat setup, or performance outboard, this ignition package provides improved spark energy, stronger ignition reliability, and the durability needed for years of service on the water.
