Hello,<br />This is my first post. Hope someone can help. <br />I have a 1989 125hp Force, M#1258W9B, S#1188. My tilt would not hold up the motor. Went to Merc site to check parts availability. Was able to order check valve "kit" F17620. Received one check valve and snap ring. I thought there should be two? When I attempted to remove the check valve that is visible from the back of the boat, what I found confused me. Out came an aluminun plug. In front of that was a steel piece with an o-ring. These are sperate pieces. I then was able to remove the center piece, shuttle valve. This gave me access to the other check valve, which I removed. This was exactly like the new check valve I ordered, one piece with needle valve and spring inside. Can anyone help me? I thought there should be two of the same valves.<br />Thanks,<br />manzi
