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.\u003c\/p\u003e\u003cp\u003eBoth 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.\u003c\/p\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAqua King II Supreme 5.0 GPM freshwater pressure pump\u003c\/li\u003e\n\u003cli\u003ePro Blaster II Ultimate 5.0 GPM washdown pump\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e5.0 GPM flow rate — handles multiple simultaneous outlets\u003c\/li\u003e\n\u003cli\u003eFully automatic operation — activates on demand, shuts off when flow stops\u003c\/li\u003e\n\u003cli\u003eElectro-coated motor for corrosion resistance in marine environments\u003c\/li\u003e\n\u003cli\u003eO-ring seals and fully sealed wire entries for moisture protection\u003c\/li\u003e\n\u003cli\u003eQuiet, smooth water delivery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e Ideal for trawlers, cruisers, and liveaboard vessels with high freshwater demand — particularly where the galley, head, and deck wash are used simultaneously.
