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.
