The SHURflo Aqua King II Standard 4139 series boat water pump design was created with unique over-moulded single-piece diaphragm and internal bypass, assuring long life and top performance in all plumbing systems.

SHURflo has built their quality reputation on the reliability and dependability of every pump they build, and with the upgraded Aqua King Standard they have built a marine pump with the same footprint as the old model to allow for easy retrofitting.
