According to Rule’s technical documents, the pump will put out 1,620gph against a 1m (3ft 4in) head or 1,300gph against 2m (6ft 8in). In other words, you lose around 20 percent of your pump’s output when it has to lift the bilge water more than 3ft and 30 percent at 6ft 8in.
How many gph bilge pump do I need?
I recommend the following total-bilge-pump capacities as rules of thumb. Boats less than 20 feet: 1,000 gph; 20 to 25 feet: 2,500 gph; 25 to 32 feet: 4,000 gph; 32 to 36 feet: 6,000 gph; 37 to 45 feet: 8,500 gph.
