    Need help with input shaft wear...

    I've recently bought a '85 Sea Ray with a 230MR. During idle there is a knocking noise at the back of the engine/transom area. I went ahead and removed the outer drive and fired the engine. THe noise is not there. THe u-joints feel tight and the gimbal bearing feels smooth. THe seal behind...
