Sierra Trigger Assembly for Mercury Mariner Outboard Ignition Repair Parts

The Sierra Trigger Assembly line offers aftermarket replacement ignition triggers (also called ignition triggers or timer base triggers) for Mercury and Mariner outboard motors. The trigger works with the stator and flywheel magnets to produce the timing signal that tells the ignition system when to fire each cylinder. It is a key part of the outboard ignition repair system, and a failing trigger can cause hard starting, misfires or a no-spark condition.

Key Features:

• Direct-replacement design for Mercury and Mariner outboard ignition systems
• Generates the crankshaft-position timing signal needed for accurate spark timing
• Built for marine use and designed to hold up in freshwater and saltwater environments
• Engineered by Sierra to meet or exceed OEM standards
• Backed by Sierra's limited lifetime warranty against defects in workmanship and materials

Sierra offers more than 6,000 premium-quality aftermarket marine parts, tools and components. Choose the individual part number that matches your engine's cylinder count and application, and use the engine's service manual for installation and testing procedures.
