  • Faster than ever. Our latest upgrades have made the drive more efficient, and that allows us to use a more aggressive prop for faster speeds
  • 3:1 Pedal drive input, fed in to a 4:1 spiral bevel gear input
  • Smoother. The new belt driven system and increased diameter in the FD cable pedals smoother than all previous versions.
  • Quieter. Upgraded bearings keep the drive whisper-quiet.
  • More Durable. Industry-tested technology make the FD tougher than ever.
  • Virtually Maintenance Free. The upper unit is now in a sealed oil bath - no more topping up the grease. All you need to do is make sure it is rinsed after every outing.
  • Tested Tough. We've logged hundreds of hours of saltwater and freshwater testing. Every drive is checked and double-checked for quality.
  • Two-Year manufacturer warranty.
You can simply upgrade ANY of Jackson's FD boats with this unit. Everything but the socket wrench is included. See the upgrade video here. 

Backwards compatible with all our FD model kayaks. Will require a complete replacement of upper and lower unit.
