Shurflo Blaster II Washdown Pump — 3.5 GPM | 45 PSI
A capable, compact washdown pump for boats where space is tight and the work is real. The Shurflo Blaster II delivers 3.5 GPM at 45 PSI through a four-chamber design that handles fish box rinse, deck scaling, anchor chain cleanup, and general cockpit washdown without complaint.
Self-priming with 6 feet of lift, it can run dry without damage and won’t overheat during extended use — two things that matter when you’re mid-cleanup and can’t stop. The sealed switch and E-coated seamless motor shell keep moisture out where it counts. A pistol grip spray nozzle and fittings are included so you can get straight to work.

Parts Desk Insights
Best use case: A solid fit for smaller fishing boats, center consoles, and day boats where a compact, ready-to-run washdown pump is needed without the footprint or cost of a larger unit. The included nozzle makes this a true out-of-the-box solution. If you need higher flow or pressure for a larger vessel or more demanding washdown work, step up to the Shurflo ProBlaster II (5.0 GPM). For a combined freshwater pressure and washdown solution, see the Shurflo High Flow System II.
