Performance & Practical Benefits

A dependable distributor sensor has a way of making your whole engine feel tighter and more refined. With this Mercury sensor in place, your motor starts with a quick, confident turn — no stalling, no uneven idle, just that familiar rumble that tells you everything is in sync. Out on the water, the timing stays clean across the entire rpm range, giving you smoother throttle transitions and better overall response.

The composite body stands up to the heat and moisture trapped inside a sterndrive compartment, while the Stainless Steel elements resist corrosion and maintain signal accuracy over time. Even after long days of running, idling, and docking, the sensor keeps delivering stable timing. It’s one of those parts that brings subtle improvements that you notice every time you come off plane or ease back into the marina.

Why Buy OEM

Ignition timing is too important to trust to guesswork. Aftermarket sensors may claim to fit, but small inconsistencies in signal strength or timing can lead to hard starts, uneven running, or poor performance when you’re trying to accelerate. A genuine Mercury Marine part eliminates the uncertainty. It’s designed to match the exact timing curve your engine expects, which means fewer headaches, fewer troubleshooting sessions, and more time spent enjoying the water. It’s the kind of part you’d recommend to another boater without hesitation.
