Mercury Champion Spark Plug QL77CC - 941

Champion Spark Plug QL77CC is a high-performance spark plug designed for use in various Mercury outboard engines. Spark plugs are critical components in your engine’s ignition system, creating the spark necessary to ignite the air-fuel mixture in the engine's cylinders. The QL77CC is specifically designed to work with many Mercury engines, offering reliability and optimal performance.

Worn or damaged spark plugs can lead to engine misfires, poor fuel economy, rough idling, difficulty starting the engine, and decreased engine performance, ultimately affecting your overall efficiency and potentially causing further damage if left ignored. It is essential to replace the spark plugs on your outboard engines every year or 300hr. These spark plugs are sold individually.
