My motor seems to spit water when the throttle is down however when I add throttle I am noticing that I am not getting a good stream of water like I should. I do believe I need a new impeller, the model number for my motor is VWB-27909B part number out of the book is 50065-1. I have looked around a few spots but haven?t had any luck. I am hoping that someone on here on the forums can help.
