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 love the smaller length of this pump and the full-length foam body. My only complaint is I wish the outflow port was designed so you could attach a hose. Pumps smooth and is very good with volume.
More compact than others, works well, good foam covering
