Cody, I had the same problem last year. The problem turned out to be the cover on the the impeller was worn on the inside and was loosing enough of its vaccume at idle to not pick up water properly. My problem was exactly as you describe yours as being. The engine would heat up at idle speed but as soon as the engine was above idle it would draw water and cool. I spent hours trying to figure out what was going on before taking it to a long time Mastercraft tech he had it figured out in about ten minutes. I think the cover was twelve bucks. Hope this helps - Rich
