Review on Bilge Manual Water Siphon Boat by Steve Arnold

Works fairly well Water flows into a pair of threaded tips Walter flows on the shaft. Times to drain the water. It is also necessary to remove the core hose to drain the storage water. I've found that by breaking off the small ribs on the bottom I can pump most of the water out of the hull efficiently. The spacer tabs allowed for plenty of air to be sucked in when you were nearing completion. I understand the idea of a prop, but it will do if the water level is high enough just to keep it at an angle.
