Score: 85/100Rankings
The Seaflo 55-Series 5.5 GPM marine water pump is a heavy-duty, self-priming diaphragm pump designed for high-volume applications in marine, RV, and off-grid settings. It delivers 60 PSI of pressure with a flow rate of 5.5 GPM, supporting up to five simultaneous outlets without requiring an accumulator tank, though one is available for reduced cycling. While it offers excellent performance and durability, the high amperage draw requires careful electrical planning.
The Jabsco HotShot HD6 is a heavy-duty, 12V diaphragm washdown pump designed for marine applications, delivering 6 GPM flow and 70 PSI pressure. It features a durable construction with a cast aluminum lower housing and co-molded TPV diaphragm, making it suitable for robust deck washing tasks on larger vessels. Best suited for marine professionals or boat owners needing high-pressure deck washing on larger vessels, specifically in saltwater environments where corrosion resistance and self-priming up to 7 ft are required.
