For high-performance boating enthusiasts and professional racers alike, the ignition system is the heart of any high-performance outboard engine. At the center of this system lies the Mercury Racing OEM ignition trigger—now available in its most refined form with part numbers 96455A10 and 96455A11.
This latest-generation trigger has been meticulously engineered for compatibility with 1976 through 1999 Mercury and Mariner V6 2-stroke outboard motors, delivering precision, reliability, and power to engines that demand the best.
The Mercury 96455-series trigger, including superseded versions like 96455A6, 96454, and even earlier models such as 68162A1, 68162A5, and 68162A8, is a cornerstone in the evolution of ignition control for Mercury outboards. Whether you're rebuilding a 150 HP XR2, upgrading a 200 HP XRi, or maintaining a 225 ProMax, this trigger is the trusted OEM solution.
Performance-focused boaters using Mercury Black Max, XR4, XR6, or high-output models like the SST-120, 245 HP Carb, 260 HP Racing engine, 2.5 EFI ROS with CDI ignition, S3000, or the drag-racing legend 300 Drag, will appreciate the seamless integration and consistent firing this part delivers.
At its core, the 96455A10/96455A11 trigger acts as the ignition system’s brain, using three internal coils to monitor the crankshaft position through interactions with dual reverse-polarity magnets set in the flywheel hub. This vital signal, once generated, is transmitted to the switch boxes, where the CDI (Capacitor Discharge Ignition) system springs into action—discharging a precise electrical pulse to the ignition coils.
This synchronizes the spark plug firing across all six cylinders with pinpoint timing, crucial for engines operating at high RPMs and under competitive load conditions.
The trigger’s performance becomes even more critical in specialized Mercury Racing outboards like the SST-120 and SST-140 race configurations. Whether you're maintaining a classic 2-stroke Mariner or pushing limits with a Mercury Racing 225 HP ProMax, the 96455A11 ignition trigger ensures your engine remains responsive, efficient, and race-ready.
This genuine Mercury OEM part—sourced from current production stock—offers peace of mind by replacing aftermarket and outdated units, including CDI Electronics part number 134-6456. Installing a factory-original 96455A11 or 96455A10 ensures compatibility, durability, and peak ignition timing.
For technicians and DIY mechanics, trigger diagnosis typically starts by confirming proper firing pair activation. Consult your factory Mercury service manual’s ignition test chart to validate signal output and troubleshoot misfires or timing issues.
In high-performance marine environments, every microsecond counts. With the Mercury 96455-A11 or 96455-A10, you're not just replacing a part—you're investing in trusted engineering built to power the most iconic names in outboard performance.
