Performance & Real-World Benefits

The 828623T6 reed assembly brings your engine’s intake system back to life. Over time, reeds can chip or lose tension, causing poor idle, hesitation, or reduced power. Replacing them with a genuine Mercury assembly restores proper air pulse timing and maximum efficiency.

You’ll notice smoother running at idle, cleaner acceleration, and a stronger pull at wide-open throttle — all while maintaining Mercury’s factory reliability.

Why Choose OEM

Mercury’s reed assemblies are cast and tuned for their specific engine designs. Aftermarket replacements might not flex or seal the same, leading to uneven airflow and reduced performance.

A genuine Quicksilver reed assembly ensures exact fit, durable materials, and the performance your OptiMax was built to deliver.
