Honda engine driven water pumps are used in agriculture, construction, emergency, flood situations, boating and personal home use. These portable water pumps are powered by durable fuel-efficient Honda four-stroke engines. Many feature Honda's exclusive OHV design, which is 30% more fuel-efficient that comparable side-valve engines. This fuel-saving, efficient design is packed with long-life features like a cast iron cylinder sleeve and a crankshaft supported by ball bearings for increased durability.
