The Harmony High Volume Bilge Pump moves more water with less fatigue. Shortened length makes for less fatiguing strokes while more efficient design moves lots of water. Low-profile exit port won't snag on deck rigging.
I bought this bilge pump because a friend let me use theirs and I loved it. I realized I was pumping like crazy and no fatigue and it was moving a ton of water out of the boat.
Just purchased this bilge pump for my kayak. I got to try it out today while doing rescue practice and I love it. This bilge pump moves a ton of water and it's easy to use. I'm a 65 yr young female that doesn't have the same muscle that I had 20 years ago but using this pump didn't tire my arms like my other pump and it really gets the water out.
