The Harmony Pedal Pump System is easily installed and will provide you with the opportunity to pump your kayak dry as you paddle. Dual pump bellows are integrated onto footpedals on your footbraces and the natural rhythm of paddling provides enough pressure on the bellows to engage constant pumping to drain the last drop of water from your boat. Great for boats with a slow leak or that sustain damage while on a trip. The bellows also provide a softer surface for feet on your pedals for added comfort. Kit includes footbrace rails, bellows, tubing, and through hull port as well as instructions.
