Sierra Trigger Assembly Outboard Ignition Repair Parts

Sierra trigger assemblies are replacement ignition components for Mercury and Mariner outboard engines. The trigger, also called a pulser coil or trigger coil, senses flywheel position and sends a timing signal to the CDI power pack. That signal tells the power pack when to fire each spark plug. A worn or failing trigger assembly can cause hard starting, misfires, a rough idle, or loss of spark on one or more cylinders.

Key Features:

• Aftermarket replacement trigger assemblies for outboard ignition system repair
• Support accurate ignition timing and consistent spark delivery
• Built for the heat, vibration, and moisture of marine use
• Made as direct replacements for the original-equipment trigger components
• Backed by Sierra's reputation for marine engine parts

Sierra has long supplied marine engine parts for outboard, sterndrive, and inboard applications. Choose the child variant that matches your engine's cylinder configuration and ignition system to restore dependable starting and smooth running.
