Sierra CDM Trigger for Mercury Outboard Engines

The Sierra CDM trigger (also called a capacitor discharge module trigger or ignition trigger) is a replacement ignition part for Mercury outboard engines. It is part of Sierra's line of marine ignition repair parts. The trigger sends the timing signal that tells the CDM or power pack when to fire the spark. It helps the engine start and run smoothly.

Key Features:

• Aftermarket replacement for the ignition trigger used in Mercury outboard ignition systems
• Helps restore reliable starting, steady idle and consistent spark timing
• Made for marine use, with Sierra's focus on fit and performance
• Available in several part numbers to cover different Mercury outboard models

Sierra is a long-established supplier of marine replacement parts for outboard, sterndrive and inboard engines. A new CDM trigger can fix hard starting, misfires, intermittent spark or a no-spark condition caused by a worn or failed trigger. Choose the individual part number that matches your engine.
