In a two-stroke outboard, the reed cage and reed petals are the core of the intake assembly. The reed petals are flexible and open and close against the reed cage to control the flow of air and fuel. 


A reed valve is a one-way valve that allows the air and fuel mixture to move from the carburetor to the crankcase during the piston's upstroke. During the piston's downstroke, the valve closes and forces the air and fuel mixture into the cylinder.


The Buckshot Racing Ported & Flowed 4-Petal Reed Cages fit all Mercury 2-Stroke V6 Outboards (4 & 5 Petal Horizontal and Vertical Reed Black Blocks) manufactured from 1976 to 2005; including all 2.0, 2.4, and 2.5 Liters.


This reed cage is another first in innovation allowing all Black Max owners to increase their performance with a bolt in part! Racers and enthusiasts understand this motor runs harder when ported and flowed. We've done the homework with this world-class product.

Why do we recommend Boyesen?


The reed petals in all 2 stroke engines undergo a significant amount of wear and tear. At peak RPM, reed petals open and close hundreds of times per second, causing a single reed to lose its ability to regulate flow rates effectively over time.


This can lead to a decrease in reed petal reaction and a loss of peak horsepower consistency. Boyesen's dual-stage reed design offers more usable power compared to stock single-stage reeds. Stock single-stage reeds are most effective within a narrow RPM range due to their design limitations.


In contrast, Boyesen's dual-stage reeds, with one soft reed on top of one firm flow-through reed, provide a wider range of intake control and increased intake velocity. The dual-stage design also allows for the replacement of the stock reed stop with a Rev-Plate, enabling the reeds to open freely and function efficiently.


The bottom reed's multi-port feature creates more channels for the charge, delivering increased velocity to the intake ports and generating more overall power.


The dual-stage reeds work together to perform efficiently throughout the entire powerband, with the difference in stiffness between the top and bottom reeds allowing for quick and accurate response to changes in engine pressure.


This results in quicker acceleration, crisper throttle response, and increased horsepower throughout the powerband.
