Shurflo High Flow System II — Dual Freshwater Pump System
Deliver consistent, high-volume freshwater pressure throughout your vessel with this complete dual-pump system. Combining a dedicated pressure pump with a high-output washdown pump, the Shurflo High Flow System II is engineered for larger boats where a single pump can't keep up with simultaneous demand from multiple outlets — galley, head, shower, and deck wash all running at once.
Both pumps are built to handle the marine environment: electro-coated motors resist corrosion, fully sealed wire entries block moisture ingress, and O-ring seals keep the system tight. The result is quiet, smooth, fully automatic water delivery that activates on demand and shuts off cleanly.
What's Included
- Aqua King II Supreme 5.0 GPM freshwater pressure pump
- Pro Blaster II Ultimate 5.0 GPM washdown pump
Key Features
- 5.0 GPM flow rate — handles multiple simultaneous outlets

Parts Desk Insights
Best use case: Ideal for trawlers, cruisers, and liveaboard vessels with high freshwater demand — particularly where the galley, head, and deck wash are used simultaneously. If you only need a single freshwater pressure pump, the Shurflo Aqua King II Fresh Water Pump is available as a standalone unit in multiple configurations. For dedicated washdown duty, the Shurflo ProBlaster II Washdown Pump is also available separately. If you need a replacement cartridge for an existing Shurflo pump, see the Shurflo Pump Replacement Cartridge.
