I just bought a small rig with a 9.9 4stroke Yamaha outboard. It was not peeing water through the tell tale when I put it in the lake. Worked fine on garden hose but they can fool you sometimes.
Anyway, I pulled the foot off and the pump is perfect. Matter of fact it came apart so easily I suspect someone had recently installed a new pump. Now I'm wondering if the did not get the pick up tube connected when they reassembled it. The vanes in the pump were oriented correctly so that wasn't the problem. Any other suggestions?
