How Reeds Work
Reeds are one-way valves controlling the amount of air/fuel mixture entering the crankcase of every outboard engine, then sealing it in to prevent it from escaping. Every two-cycle outboard has them. But the stock reeds in an outboard have a single-stage design that limits their efficiently. That's why stock outboards often cough and sputter at idle, fail to deliver a good hole shot, feel boggy or lifeless under throttle application, burn too much fuel or lack top-end punch. Plus, standard reeds are made of metal. Should one break, it could cause extensive damage to the outboard.
Reeds here are different and better! Each manufacturer feature a patented dual-stage design allowing every reeds to respond instantly to any change in air/fuel flow as it is accelerate or back off the throttle. As a result, a dramatic increase in efficiency and performance across the entire power band, from start-up to flat out!
Featured Product:
Boyesen reed The unique Boyesen reed provides superior response, allowing the reeds to respond quickly and accurately to changes in engine pressure. The fibreglass bottom reed provides durability for increased life over traditional all carbon reeds. Every Boyesen Reeds deliver the largest horsepower and torque gains any reed can offer.

Information
Offers maximum performance. Better throttle response throughout the range.
Reed's patented design incorporates a specially shaped top reed and a ported bottom reed. The top reed is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom reed is ported to provide maximum flow and horsepower at higher RPMs. The track-proven advantages include:
More Airflow: The dual-stage design allows to replace every stock reed stop with a Rev-Plate, which permits the reeds to open freely and function efficiently.
More Air Velocity: The multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports.
More Overall Power: The precise difference in stiffness between the top reed and the bottom reed inables the system to respond quickly and accurately to changes in engine pressure for maximum airflow and responsiveness throughout the entire powerband.
