CDI Electronics 134-9527-2 Ignition Trigger for 2-Cylinder Mercury Mariner Outboards

The CDI Electronics 134-9527-2 is an ignition trigger built for 2-cylinder Mercury and Mariner outboard motors. The trigger is a core component of the outboard's ignition system, working with the flywheel to signal spark timing to the powerhead. As a wear item exposed to vibration, heat, and moisture inside the lower cowling, the trigger can degrade over time and cause misfires, hard starting, or a no-spark condition, making replacement with a correctly specified part like the 134-9527-2 important for restoring reliable ignition performance.

This trigger is specified for 2-cylinder Mercury Mariner outboard applications and is sold as a direct-fit replacement component rather than a universal part. It is a compact, lightweight unit designed to be installed in the same location as the original equipment trigger it replaces, with no re-wiring or ignition system modification required beyond a standard swap.
