[QUOTE="mcgovern61, post: 2801, member: 59"] The impeller would have to be a reverse vane to pump backwards when the pump is turning the right way. Of course, my assumption is that you have verified that it is turning the right way. We had a firepump on a tug running at 50 psi when it should have been at a minimal 75 psi. Ran that way for 8 years and no one bothered to find out why. I got onboard and did not accept the pressure and found out the rotation was backwards (3 phase wired out of phase). Changed the wiring and corrected the rotation and it pumped up to 120 psi! Point is, it ran backwards for years, pumped water but ran hot at the housing because the impeller was cavitating significantly. I would think that it would be unlikely that the pump is running backwards because that would assume Honda changed the rotation on the 1200 from the 1100. However, a wrong impeller on a replacement pump is very common. [/QUOTE]
