CDI Electronics 136-7029-5 Force Trigger Sensor - 5 Cyl., Replaces Mercury 817029A 5, 817029A 6, Fits 1991-1992 150 HP

The CDI Electronics 136-7029-5 is a 5-cylinder trigger sensor engineered for Force outboard engines, designed as a direct replacement for the Mercury 817029A 5 and 817029A 6 trigger units. The trigger sensor is a core component of the ignition system, responsible for signaling the correct firing point to each cylinder as the flywheel rotates. A worn, cracked, or failing trigger can cause hard starting, misfires, rough idle, or a no-start condition, making this a common maintenance and troubleshooting replacement part.

This trigger is built to match the original 5-cylinder configuration used on the covered Force 150 hp models, ensuring the sensor timing and mounting match factory specifications. Because ignition timing accuracy directly affects engine performance and fuel efficiency, using a properly matched trigger sensor like the 136-7029-5 helps restore smooth, reliable operation to the outboard's ignition system.

The 136-7029-5 is intended specifically for 1991-1992 150 hp Force outboards across the listed engine models, and it directly replaces the Mercury-numbered 817029A 5 and 817029A 6 triggers, making it straightforward to cross-reference when ordering.
