Sierra Ignition Pack for Mercury Outboard Engines

The Sierra Ignition Pack line (also called a power pack, switch box or ignition control module) provides aftermarket replacement ignition components for Mercury, Mariner and Force outboard engines. The ignition pack controls spark timing and delivers the firing signal to the coils. A worn or failed unit can cause hard starting, misfires, a weak or missing spark, or a no-start condition. Replacing it can restore reliable engine performance.

Key Features:

• Aftermarket replacement engineered to meet or exceed OEM standards
• Built to hold up in harsh marine environments
• Designed as a direct replacement for the original ignition pack, so no modification is needed
• Interchanges with original Mercury and CDI ignition pack part numbers (listed on each individual item)
• Backed by Sierra's limited lifetime warranty against defects in workmanship and materials

Sierra provides premium-quality aftermarket replacements for over 6,000 marine parts, tools and components. Choose the correct item in this product line for your engine's cylinder count and application to keep your outboard's ignition system running dependably.
