The name says it all. More compact and powerful than conventional kayak pumps, the Harmony High Volume Bilge Pump’s shorter length (16″) makes for less fatiguing strokes and its innovative design pumps 30% more water per stroke. Its full length foam sleeve provides horizontal top-of-the-water flotation and comfortable hand grip. Synthetic barrel and shaft mean no corrosion. OK, maybe the name didn’t say it all, but it says a lot.
