This is my 3rd Honda pump and biggest. When I first started it water sprayed from the pump seal and I thought dang I got a bad one like I saw another reviewer say. I tightened the bolts and ran it at lower RPM for the first day with just a small amount of leakage. After it got broke in I can run it at full speed with no leakage. I’m filling a half acre farm pond and it gets used every day several hours a day. Very happy with it.
