Shurflo Aqua King II Fresh Water Pump — 3.0 GPM
Dependable freshwater pressure for smaller boats and simpler plumbing setups. The Shurflo Aqua King II delivers smooth, consistent flow to your galley or head without the pressure swings or constant on/off cycling that come with basic diaphragm pumps.
The built-in mechanical bypass adjusts output to match demand automatically, so the pump runs quietly at low flow without hunting or pulsing — and there’s no need for a separate accumulator tank. The motor is built to handle the marine environment and can run dry without damage if the tank runs low.
Key Features
- Mechanical bypass varies flow rate automatically — no accumulator required
- Smooth, quiet operation at low flow without cycling
- Electro-coated seamless motor shell resists corrosion
- O-ring sealed end bells and fully sealed wire entries on motor and pressure switch
- Dry-run safe — pump will not be damaged if run without water
- Ignition protected and thermally protected
- Includes inlet strainer and 1/2" hose barb fittings
Parts Desk Insights
Best use case: The right fit for smaller cruisers, day boats, and runabouts with one or two water outlets and modest flow demand — a galley tap and a single head. If your vessel has more fixtures or you need higher simultaneous flow, step up to the Shurflo Aqua King II 4.0 GPM or the Shurflo Aqua King II Supreme 5.0 GPM. For a complete freshwater and washdown dual-pump package, see the Shurflo High Flow System II. Need a replacement part for an existing Shurflo pump? See the Shurflo Pump Replacement Cartridge.
