Information About 332-2986A21
The 332-2986A21 is a CDI-style ignition switch box used in older Mercury and Mariner outboard engines equipped with battery ignition systems. It receives electrical energy from the stator under the flywheel and distributes timed high-voltage signals to the ignition coils for spark plug firing. The module is commonly used on 1967–1979 Mercury outboards ranging from approximately 50HP to 150HP, including inline-6 engines such as 90, 115, 125, 140, and 150 HP models. This electronic unit is mounted on the engine block and serves as a key component in the ignition system responsible for maintaining proper spark timing and engine operation.
Key Features:
- Ignition Control Module: Controls spark timing by distributing electrical pulses to ignition coils.
- Mercury OEM Component: Designed to original Mercury Marine specifications for reliable ignition performance.
- Battery Ignition System Compatibility: Designed for engines using battery-powered ignition systems.
- Multi-Engine Fitment: Compatible with many Mercury and Mariner 4- and 6-cylinder outboards produced from the late 1960s through the late 1970s.
- CDI-Type Ignition Operation: Receives energy from the stator and triggers spark generation through the ignition coils.
- Engine Performance Support: Helps maintain proper spark timing for efficient combustion and smooth engine operation.
- Durable Electronic Housing: Built to withstand vibration and heat present in marine engine environments.
The 332-2986A21 delivers the reliability and precision required for consistent ignition timing and spark generation in marine outboard engine ignition systems.
