MARK IV EVOLUTION
Meet the Flex Drive Mark IV, the latest innovation in the Flex Drive evolution. The only drive system on the market to offer a shallow water auto-retracting lower unit, a three-position dagger board to accommodate a variety of depths, and a sealed above-water pedal system with intuitive forward and reverse operation – all wrapped up with Jackson Kayak’s industry-leading warranty and customer service.
Faster, smoother, quieter, and more durable than ever before, the Flex Drive Mark IV gives you the power to get closer to the action.
So, how did we take something great and make it even better?
The Mark IV is faster—period. A 3:1 pedal drive paired with a 4:1 spiral bevel gear system powers a more aggressive prop, translating every pedal stroke into maximum speed. The result is smooth, efficient power that gets you where you need to go, faster than any previous FlexDrive.
Silent operation starts below the waterline—upgraded bearings, a larger-diameter cable, and reversed rotation eliminate underwater noise. Above the surface, the completely redesigned belt-driven upper unit delivers the smoothest, quietest performance in FlexDrive history.
We engineered the Mark IV using proven bicycle drivetrain components—technology that's been refined for over 100 years. These components are housed in a sealed, maintenance-free oil bath with a serpentine belt system that delivers superior strength and forgiveness under load.
Hundreds of hours of real-world testing in fresh and saltwater confirmed what we already knew—the Mark IV is built to last. That's why it's backed by our 2-year manufacturer warranty, just like every FlexDrive before it.
