If you’re running a Mercury 2.5L Laser Injection EFI and want a stronger, more precise foundation for your reed system, this is the upgrade built for you. The Billet Mercury 7-Petal EFI Laser Injection Reed Plate is a limited special from Ox Performance and Buckshot Racing #77, designed specifically for Mercury’s 7-petal Laser Injected 2-stroke outboards, including the 225HP Pro Max.
Our Billet Reed Plate replaces the Mercury OEM 12124-A3 reed plate and is intended for owners who care about reliability,and build quality—whether you’re refreshing a proven lake motor, tightening up a performance setup, or assembling a stronger EFI intake combination.
What This Billet Reed Plate Does (and Why It Matters)
On a 2-stroke EFI outboard, the reed system is a critical gateway for airflow and crankcase pulse behavior. Over time, factory parts and older components can show wear, fatigue, or inconsistencies that may affect how the engine responds. A billet reed plate is valued because it’s built for rigidity and precision, helping provide a stable platform for your reeds and cages—especially in higher-stress performance use.
This is not just a “replacement part.” It’s a build-quality upgrade meant to support a cleaner, more consistent reed assembly foundation in a Mercury 2.5L Laser Injection EFI application.
Designed for Mercury 2.5L Laser Injection EFI (7-Petal)
This reed plate is engineered specifically for Mercury 2.5 Liter 7-petal motors manufactured from 1991–2005 equipped with Laser Injection EFI. If your engine is a Laser Injection 2.5L and uses the 7-petal arrangement, you’re in the correct neighborhood for fitment.
Because Mercury 2.5L builds can vary—especially after years of owner modifications—confirm your current intake and EFI style before ordering. If your setup is carbureted, a different EFI system, or a 5-petal configuration, this reed plate typically will not be the correct match.
OEM Reference: 12124A3
This product is referenced to Mercury OEM part number 12124A3. That OEM number matters because it’s how many builders and parts lookup systems cross-check compatibility on Mercury Racing and Pro Max variants. If your existing part or documentation references 12124A3, this billet reed plate is designed as the correct style replacement/upgrade for that application.
When It’s Time to go 7-Petal Reed Plate
Many owners don’t look at the reed plate until they’re already deep into an intake refresh. In reality, it’s worth considering replacement or upgrading when you’re already servicing reeds/cages, chasing inconsistent response, rebuilding after hours of use, or trying to make a high-quality EFI setup more dependable.
If you’re already planning to replace reeds or move to billet cages, installing a billet reed plate at the same time can help ensure your intake assembly is refreshed as a system rather than piecemeal.
Recommended Pairing: Billet Reed Cages and Reeds
This billet reed plate is a strong base, but the reed system works best when components are matched. Recommended billet reed cages and reeds are also available on this site, and many performance-minded builders prefer installing these together to simplify fitment, improve overall assembly quality, and avoid mixing tired parts with new upgrades.
If you’re building for performance or longevity, pairing the reed plate with fresh reeds—and especially billet cages when appropriate—can be the difference between an intake refresh that’s “good enough” and one that feels truly complete.
Made in the USA (Build Quality You Can Stand Behind)
This billet reed plate is designed and made in the USA, with the kind of machining focus that performance outboard owners expect. It’s built as a purpose-driven Mercury 2.5L Laser Injection EFI component—something you can install with confidence in a serious 2-stroke setup.
