I purchased 2 dw180 pumps off this company ($1066) they have been a nightmare. First off the threds on the bolts supplied were wrong so i had to get my threds on my gx200 drilled and tapped ($200). I then fit the water pumps to my motors to have the impellers spin off and destroy the water seal and rip the thread from the impeller because the stands supplied were too long. I then purchased a secon impeller off them for a extra $328 dollards. then the second pump did the same as the first. They told me to replace the shaft in my motor to suit the pump. (yet it was advatised to fit a honda gx200). im now having to get the impellers and the pump stands worked on by a local engineer because they wont reimburse me for any of the broken parts. Do yourself a favor and just buy quality products for a quality company.
