Put alot of money in this but finally got it going, new impellar was one, it has been pumping water just fine , it is something I always check when I first start it every time I dump it in the water. While it is warming up. The boys have been running it lately and now they say it does'nt put any water out a low rpms, but does when you get it going down the lake. Could the new impellar be gone already or is my water pump going bad? I hope they haven't ruined it by getting it hot.
