The crew of the 40-foot sailboat Uma tests and compares two freshwater pumps, the Johnson Aqua Jet SPX Flow WPS 4.0 and the Marco UP/E, to replace a noisy Jabsco unit.0:28 The Marco pump features variable speed control and a low-water shut-off, while the Johnson model requires an external accumulator tank.0:42 Testing reveals that the Marco pump produces a consistent, lower-decibel hum at partial flow, whereas the Johnson pump cycles on and off, creating intermittent noise.11:02 To mitigate vibration, the crew mounts the Marco pump on a double-isolated HDPE board, using rubber feet to decouple the unit from the bulkhead.20:52 They also identify that flexible hose runs of at least 30 centimeters help dissipate vibration before it reaches rigid plumbing.19:57 The crew concludes that the Marco pump provides a quieter, more reliable solution for their freshwater system.
