I just bought a 750sx. I don't know a lot about it. There are two black fittings on the nose of the ski. I know the one on the left is the bypass outlet. When I first started it there was no water coming out and I found that the fitting was plugged. I cleaned it out and now there is water flow but I don't know how much flow its supposed to have? It is a steady stream but only shoots out about an inch and runs down the bumper. Also, what is the fitting on the right side for? It bubbles occasionally with the engine running but nothing comes out, is that normal? Is there a bilge pump on a 750sx?
