News Release

Tokyo, July 15, 1998 - The new 1.5-inch caliber 4-cycle WX15 water pump, which features Honda's newly developed GXH50 compact 4-cycle engine, will go on sale on July 28 at Honda Power Products dealers throughout Japan. The new GXH50 power unit is as lightweight and compact as a 2-cycle engine. In fact, within the stationary-type 2.5PS class, it is the lightest and most compact engine in the world.
The WX15 features extremely quiet operation, easy start-up, and emission of minimal exhaust gases. A one-touch coupling is a standard feature in the WX15 series. Easy for anyone to use, it has a wide range of applications-from agriculture and industrial settings to sports and leisure functions.
